SIMPLE Photometry Catalog
The Spitzer IRAC/MUSYC Public Legacy Survey in the Extended Chandra Deep Field South (SIMPLE) consists of deep IRAC observations (several hours per pointing) covering the 0.5 x 0.5 deg area surrounding the GOODS CDF-South. This low-background region of the sky has by far the best supporting data of any cosmological survey field of comparable area, with deep observations from the X-rays to the thermal infrared.
SAGE-SMC IRAC Single Frame + Mosaic Photometry Catalog
The SAGE-SMC pro ject is a Cycle 4 legacy program on the Spitzer Space Telescope, entitled, SAGE-SMC: Surveying the Agents of Galaxy Evolution in the Tidally-Disrupted, Low-Metallicity Small Magellanic Cloud, with Karl Gordon (STScI) as the PI. The project overview and initial results are described in a paper by Gordon et al. (2010, in prep). The SMC was mapped at two different epochs dubbed Epochs 1 and 2 separated by 3 (IRAC) and 9 (MIPS) months, as this provides a 90-degree roll angle in the orientation of the detectors, which optimally removes the striping artifacts in MIPS and artifacts along columns and rows in the IRAC image data. In addition, these two epochs are useful constraints of source variability expected for evolved stars and some young stellar ob jects (YSOs). The IRAC and MIPS observations from the S3MC pathfinder survey of the inner 3 sq. deg. of the SMC (PI: Bolatto, referred to as Epoch 0) have been reduced using the same software. In comparison to the catalog, the archive has more source fluxes (fewer nulled wavelengths) and some more sources but these additions have more uncertainty associated with them. For the catalog, a source must be detected in at least 60% of the observations at that wavelength, at least 32% of the observations in an adjacent band (the confirming band), and the S/N must be greater than [5, 5, 5, 7] for IRAC bands [3.6um], [4.5um], [5.8um] and [8.0um]. The 2MASS K_s band is counted as a detection. For a typical source, extracted from 2x12 sec frametime images, the minimum detection criterion amounts to being detected twice in one band (usually band 1 or 2) and once in an adjacent band (sometimes referred to as the 2+1 criterion). For the catalog, sources with neighbors within a 2" radius are excluded (culled). For the archive, sources within a 0.5" are excluded. For more details, see Section 3.3 of the SAGE-SMC Data Delivery Document.
COSMOS ACS I-band Photometry Catalog
COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.This is the ACS catalog for the COSMOS survey that has been constructed from 575 ACS pointings. Please see Leauthaud et al. 2006, ApJ, for project and data details.
DEEP IMPACT MRI PHOTOMETRY OF COMET 9P/TEMPEL 1 V1.0
This dataset contains photometric measurements of comet 9P/Tempel 1 from images taken with the Medium Resolution CCD Instrument during the approach phase of the Deep Impact mission (from 1 May 2005 to 4 July 2005). These data, based on circular apertures ranging from 5 to 30 pixels in diameter, were derived from both science and navigation images taken through clear filters.
IHW COMET HALLEY INFRARED PHOTOMETRY V1.0
NASA's International Halley Watch (IHW) has created a Comet Halley Archive. The collection of data spans the full wavelength range as submitted by scientists to the IHW. The observations belong to one of the following Disciplines: Amateur, Astrometry, Infrared Studies, Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, and Spectroscopy and Spectrophotometry. The data collected by these nine disciplines were augmented by Spacecraft measurements. The data were submitted to IHW, but the evaluation and selection for the Archive has been the primary responsibility of the Discipline Specialist Teams for each network in cooperation with the Lead Center. The data from the Infrared Photometry subnetwork contains 2204 observations spanning dates from 1984 September 14 through 1988 April 08.
DEEP IMPACT: IRAS PHOTOMETRY OF COMET 9P/TEMPEL 1
This data set contains photometry of comet 9P/Tempel 1 as derived from reprocessed IRAS images from 1983, in support of the NASA Deep Impact Mission.
ANS Ultraviolet Photometry Catalog of Point Sources
All reliable observations of point sources with the ultraviolet photometer onboard the Astronomical Netherlands Satellite (ANS) operating between the October 1974 and April 1976 are presented. Extended objects, non-detected objects, and objects at the edges of the instrument's field of view have been omitted. The catalog contains 3573 objects, mostly stars (the total ANS UV database contained 4800 observed positions). The ANS satellite observed in five UV channels centered around 150, 180, 220, 250 and 330 nm (1500, 1800, 2200, 2500 and 3300 Angstroms). The characteristics of the ANS UV photometric bands are: <pre> Band designation 15N 15W 18 22 25 33 ------------------------------------------------------------------------- Central wavelength (nm) 154.5 154.9 179.9 220.0 249.3 329.4 Bandwidth (nm) 5.0 14.9 14.9 20.0 15.0 10.1 </pre> The reported magnitudes were obtained from mean count rates converted to fluxes using the ANS absolute calibration of Wesselius et al. (1980A&A....85..221W). In addition to the ultraviolet magnitudes, the catalog contains positions taken from the satellite pointing, spectral types, and UBV data from other sources as well as comments on duplicity, variability, and miscellaneous notes concerning individual objects. Within the ANS photometric system, the UV magnitudes of different objects are comparable down to a level of 0.5-1.0%. Several studies on the intercomparison of all ANS data, and on the comparison of the ANS data with stellar models, with other UV satellites, and with the expected UV fluxes on the basis of ground-based information alone suggest that the ANS photometric system is well-established, and has, in particular, a linear dynamic range of at least a factor of 20,000. In these two respects, repeatability and dynamic range, the ANS UV instrument far exceeded all other UV missions then extant, e.g., TD-S2/68, OAO-WEP, and IUE. Of course, ANS had a much poorer spectral resolution, about 15 nm (150 Angstroms), than the other instruments. This table was created by the HEASARC in September 2011 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/97">CDS Catalog II/97</a> file ans.dat.

SAGE IRAC Single Frame + Mosaic Photometry Catalog
The Spitzer Space Telescope Survey of the Large Magellanic Cloud Legacy Project Surveying the Agents of a Galaxy's Evolution (SAGE) traces the life cycle of observable matter that drives the evolution of a galaxy's appearance. SAGE has revealed over 6 million sources including ~150,000 evolved stars, ~50,000 young stellar objects and the diffuse interstellar medium with column densities > 1.2×1021 cm -2. The data will provide fundamental insights into the physical processes of the interstellar medium, the formation of new stars and the injection of mass by evolved stars and their relationships on the galaxy-wide scale of the Large Magellanic Cloud.In comparison to the catalog, the archive has more source fluxes (fewer nulled wavelengths) and some more sources but these additions have more uncertainty associated with them. For the catalog, the S/N must be greater than [6, 6, 6, 10] for IRAC bands [3.6um], [4.5um], [5.8um] and [8.0um] for the flux to appear in the corresponding wavelength column. Whereas for the archive, the S/N must be greater than [5, 5, 5, 5] for IRAC bands [3.6um], [4.5um], [5.8um] and [8.0um]. For the catalog, sources with neighbors within a 2" radius are excluded (culled). For the archive, sources within a 0.5" radius are excluded. The difference in criteria for the catalog and archive creation is more complex and described in Section 5.2 of the SAGE Data Delivery Document.

MUSYC Photometry Catalog
The Multiwavelength Survey by Yale-Chile (MUSYC) consists of deep optical medium-band and broadband optical and near-IR imaging of the ~30'x30' Extended Chandra Deep Field South. This field includes the GOODS-South field and the Hubble Ultra Deep Field, and covers the same area as the SIMPLE Spitzer Legacy program.
GALEX/COSMOS Prior-based Photometry Catalog
COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.This catalog was created using u*-band priors and the EM-algorithm. Appropriate references for a description of the method are: Guillaume, M. et al. 2006, Proceedings of the SPIE, Volume 6064, pp. 332-341. This is the current reference, and contains all the basics of the method and algorithm. A more specific reference for this catalog is Zamojski et al. (2008).The algorithm was run on the four NUV and the four FUV GALEX images covering the COSMOS field. It was run on the "-int" images (intensity maps) obtained as a product of the GALEX pipeline processing, version 1.61. The u*-band mosaic image and SExtractor catalog used as priors in this run were generously provided by Henry McCracken (IAP) and are based on CFHT-u* observations of the COSMOS field.
FEPS Photometry Catalog
The Formation and Evolution of Planetary Systems (FEPS) Spitzer Legacy program was designed to char- acterize the evolution of circumstellar gas and dust around solar- type stars between ages of 3 Myr and 3 Gyr. To achieve these goals, FEPS obtained spectrophotometric observations with the Spitzer Space Telescope for a sample of 328 stars (see Meyer et al. 2006 for a description of the sample). The observing strategy was to measure the spectral energy distribution (SED) between wavelengths of 3.6 and 70 um with IRAC and MIPS photometry, and between 8 and 35 um with low-resolution IRS spectra.

NEAR-INFRARED PHOTOMETRY OF ASTEROIDS FROM DENIS
The DENIS program (Deep European Near-Infrared southern sky Survey) was a ground-based survey of the southern sky with the aim of providing an extensive I,J,Ks photometric catalog of point and extended sources. It was carried out at the 1.0 meter ESO telescope at La Silla, Chile from late 1995 through the end of 1999. This data set contains the DENIS I,J,Ks photometry for 2000 known asteroids identified in the DENIS catalog.
Visual Imaging and Photometry of (29981) 1999 TD10 V1.0
The outer solar system object (29981) 1999 TD10 was observed in the R band in September 2001, and in B, V, R, and I in October 2002. We derive B-V=0.80+/-0.05mag, V-R=0.48+/-0.05mag, and R-I=0.44+/-0.05mag. Combining our data with the data from Rousselot et. al. 2003, we derive a synodic period of 15.382+/-0.001hr in agreement with the period from Rousselot et. al. 2003. Our observations show no evidence of a coma.
