DAWN FC2 CALIBRATION IMAGES V1.0

Abstract ======== Framing Camera 2 is one of two identical units flying on Dawn spacecraft. This dataset includes the image files to be used in the calibration of the raw data throughout the mission. These files represent the behaviour of each individual pixel with respect to dark current generation and pixel-to-pixel non-uniformity as a function of the filter. As these are elaborated image products, not obtained from a specific image acquisition, they do not have any ancillary data.

EPOXI MARS OBS - MRI CALIBRATED IMAGES V1.0

This data set contains calibrated 750-nm filter images of Mars acquired by the Deep Impact Medium Resolution Visible CCD (MRI) for the EPOCh project during the second cruise phase of the EPOXI mission. One set of observations was acquired on 20-21 November 2009 to characterize Mars as an analog for extrasolar planets. The observing period lasted approximately 24 hours, and one MRI image was taken simultaneously with the first north/south scan of the HRI IR spectrometer at half-hour intervals to provide context for the spectral scans.

MESSENGER MDIS CALIBRATED DATA RECORD V1.0

Abstract ======== The Mercury Dual Imaging System (MDIS) consists of two cameras, a Wide Angle Camera (WAC) and a Narrow Angle Camera (NAC), mounted on a common pivot platform. This dataset includes the Calibrated Data Record (CDR) version of valid images than can be turned into physical units, that were acquired during the cruise phase to Mercury, and includes post- launch checkout images, flyby images of Earth, Venus, Mercury, images acquired from Mercury orbit, and inflight calibration images. This CDR dataset is the product of conversion of raw data (Experiment Data Records, or EDRs) to one of three options: physical units of radiance; or radiance factor or I/F, with or without an empirical correction for time variable instrument responsivity. In addition to the imagery, anciliary information (including calibration files used to calibrate the data) is included.

VG2 SAT LECP CALIBRATED RESAMPLED SECTORED 15MIN V1.0

This browse data consists of resampled data from the Low Energy Charged Particle (LECP) experiment on Voyager 2 while the spacecraft was in the vicinity of Saturn. This instrument measures the intensities of in-situ charged particles (>26 keV electrons and >30 keV ions) with various levels of discrimination based on energy, mass species, and angular arrival direction. A subset of almost 100 LECP channels are included with this data set. The LECP data are globally calibrated to the extent possible (see below) and they are time averaged to about 15 minute time intervals with the exact beginning and ending times for those intervals matching the LECP instrumental cycle periods (the angular scanning periods). The LECP instrument has a rotating head for obtaining angular anisotropy measurements of the medium energy charged particles that it measures. The cycle time for the rotation is variable, but during encounters it is always faster than 15 minutes. For this browse data set only scan average data is given (no angular information).

EPOXI 103P/HARTLEY2 ENCOUNTER - HRIV CALIBRATED IMAGES V1.0

This dataset contains calibrated clear-filter images of comet 103/P Hartley 2 acquired by the High Resolution Visible CCD (HRIV) from 05 September through 26 November 2010 during the Hartley 2 encounter phase of the EPOXI mission. Four color-filter sets (350-950 nm) were acquired during the hour about closest approach.

2MASS Calibration Merged Point Source Information Table

Photometric calibration for 2MASS was performed using observations of calibration fields made at regular intervals during each night of survey operations. Measurements of standard stars in the fields were used to derive the photometric zero point offsets as a function of time during each night. Atmospheric extinction coefficients were derived from 2MASS observations made over long periods.2MASS calibration fields, or tiles, are 1° long in declination and approximately 8.5' wide in right ascension. There are 35 regular survey calibration fields distributed at approximately two hour intervals in right ascension near declinations of approximately -30°, 0° and +30°. An additional five calibration fields were defined in and around the Large and Small Magellanic Clouds to support the deep observation (6x) campaign towards the end of survey operations.Over the course of the survey, the regular calibration fields were scanned between 562 and 3692 times in nominally photometric conditions. Equatorial fields were observed from both observatories, so were observed more frequently than those near ±30° which were observed with only one telescope. The special Magellanic Cloud calibration fields were observed 108 to 468 times between November 2000 and February 2001.The following table contains brief descriptions of the entries in the Survey, 6x and Calibration Merged Point Source Information Tables. The merged source tables contain the mean positions magnitudes and uncertainties for sources detected multiple times in each of the 2MASS data sets. The merging was carried out using an autocorrelation of the respective databases to identify groups of extractions that are positionally associated with each other, all lying within a 1.5" radius circular region. A number of confirmation statistics are also provided in the tables that can be used to test for source motion and/or variability, and the general quality of the merge.

EPOXI EXOPLANET TRANSIT OBS - HRIV CALIBRATED IMAGES V1.0

This data set set contains calibrated images of eight known transiting extrasolar planetary systems (hot Jupiters) acquired by the Deep Impact High Resolution Visible CCD during the EPOCh phase of the EPOXI mission. From 22 January through 31 August 2008 the HRIV CCD collected over 172,000 usable, photometric-quality visible light images of these transiting planet systems: HAT-P-4, HAT-P-7, GJ 436, TrES-2, TrES-3, XO-2, XO-3, and WASP-3. Time series of continuous 50-second integrations were used with the clear filter (#6) to observe each system for about three weeks, typically covering five or more transits as well as secondary eclipses. An exception was XO-3 which was only observed briefly due to the spacecraft entering safe mode. The transiting planet systems were observed in the integrated light of the planet and star; no spatially resolved image of the planet was possible.

2MASS Calibration Point Source Working Database

Photometric calibration for 2MASS was performed using observations of calibration fields made at regular intervals during each night of survey operations. Measurements of standard stars in the fields were used to derive the photometric zero point offsets as a function of time during each night. Atmospheric extinction coefficients were derived from 2MASS observations made over long periods.2MASS calibration fields, or tiles, are 1° long in declination and approximately 8.5' wide in right ascension. There are 35 regular survey calibration fields distributed at approximately two hour intervals in right ascension near declinations of approximately -30°, 0° and +30°. An additional five calibration fields were defined in and around the Large and Small Magellanic Clouds to support the deep observation (6x) campaign towards the end of survey operations.Over the course of the survey, the regular calibration fields were scanned between 562 and 3692 times in nominally photometric conditions. Equatorial fields were observed from both observatories, so were observed more frequently than those near ±30° which were observed with only one telescope. The special Magellanic Cloud calibration fields were observed 108 to 468 times between November 2000 and February 2001.Calibration scan Atlas Images, and Point and Extended Source Working Databases (Cal-PSWDB and Cal-XSWDB), analogous to those from the main survey, were produced from the calibration scan pipeline data reduction. The calibration Image Atlas and WDBs are the fundamental processing archives of the data from 73,230 calibration scans taken in photometric conditions during 2MASS survey operations. The Cal-WDBs contain positions, magnitudes and characteristics of 191,464,020 and 403,811 point and extended "source" extractions, respectively. The calibration Image Atlas contains 878,769 FITS images in the three survey bandpasses redundantly covering ~5 deg2 of sky. Unlike the main survey and 6x observations, "Catalogs" have not been derived from the Calibration WDBs.
