ASTEROID ABSOLUTE MAGNITUDES

Absolute magnitudes and slopes, mostly IAU-adopted with exceptions noted, for all asteroids numbered as of the 2008 April 20 batch of Minor Planet Circulars.

ASTEROID RADAR V17.0

This data set is intended to include all published groundbased asteroid radar detections. The file is based on the collection of asteroid radar detections established by Steven J. Ostro and currently maintained by Lance A.M. Benner. The file includes disc-integrated radar properties extracted from the published papers.

FIEBER-BEYER IRTF MAINBELT ASTEROID SPECTRA V3.0

The data set contains observations obtained with the NASA IRTF SpeX instrument covering the 0.7 to 2.5 micron near-infrared portion of the spectrum. The data set archives reduced, calibrated spectra which were obtained and used in Sherry Fieber-Beyer's Ph.D. dissertation at the University of North Dakota and archives reduced, calibrated spectra subsequent 2010. The research focused on asteroids in a zone centered on the 3:1 resonance. These spectra were used to mineralogically characterize asteroids in this zone in an attempt to identify their meteorite analogs.

The dataset includes the lightcurves in digital form and a table of references to all original publications.

Absolute magnitudes and slopes, mostly IAU-adopted with exceptions noted, for all asteroids numbered as of the 2006 March 14 batch of Minor Planet Circulars.

SAWYER ASTEROID SPECTRA V1.1

Partial spectral data for the plots presented in S. Sawyer's PhD Thesis, 'A High Resolution Spectroscopic Survey of Low Albedo Main Belt Asteroids', 1991.

SMALL MAIN-BELT ASTEROID SPECTROSCOPIC SURVEY, PHASE II

This data set contains visible-wavelength (0.435-0.925 micron) spectra for 1341 main-belt asteroids observed during the second phase of the Small Main-belt Asteroid Spectroscopic Survey (SMASSII) between August 1993 and March 1999. The purpose of the SMASSII survey was to provide a new basis for studying the compositional diversity and structure of the asteroid belt. Based on experiences gained from the earlier SMASS survey, SMASSII focused on producing an even larger, internally consistent set of CCD spectra for small (D < 20 km) main-belt asteroids. The observing strategies and procedures used during SMASSII roughly parallel those used in the first survey (Xu et al. Icarus 115 1-35, 1995 [XUETAL1995]), though several minor changes were made in instrumentation and in portions of the data reduction process.

ASTEROID LIGHTCURVE DERIVED DATA V12.0

This is a compilation of published rotational parameters derived from lightcurve data for asteroids, based on the Warner et al. (2009) Asteroid Lightcurve Database. This is the version released on Mar. 2, 2011. In addition to reported rotational parameters by individual paper, there is a summary file with the values adopted by Harris, Warner, and Pravec as the most likely correct values for each asteroid. The data set also contains files listing known binary asteroids and 'tumbling' asteroids.

UBV MEAN ASTEROID COLORS

This data set is a compilation of mean U-B and B-V color indices of asteroids, collected from the published literature and from the unpublished Lowell Observatory UBV Asteroid Survey.

POLARIMETRY OF ASTEROID ITOKAWA

This data set contains the polarimetry of asteroid 25143 Itokawa published in Cellino et al. (2005). The observations were made from June 26 through July 3, 2004 with the Torino photopolarimeter at the 2.15 m telescope of the El Leoncito Observatory in Argentina. The degree of linear polarization was measured in five filters (Johnson-Cousins UBVRI).

LEBOFSKY ET AL. 3-MICRON ASTEROID DATA V1.2

3-micron spectrophotometric data on asteroids collected from several papers by Lebofsky, Jones, and Feierberg and their collaborators, published 1980-1990.

GALILEO ORBITER ASTEROID AND COMET SL9 SOLID STATE IMAGING 2

This data set has been generated by NASA's Galileo Project in order to distribute the images acquired by the Solid State Imaging (SSI) camera to the scientists and later to the Planetary Data System (PDS). The collection resides on volume GO_0016 and consists of all images acquired by the Galileo spacecraft during the period from the flyby of Ida through the Shoemaker-Levy 9 (SL9) comet impact on Jupiter. This includes data from SCLK 197327200 through 249221800 and contains the following targets: stars, Ida and Jupiter.

ASTEROID OCCULTATIONS V11.0

This data set is intended to include all reported timings of observed asteroid, planet, and planetary satellite occultation events as well as occultation axes derived from those timings by David W. Dunham and David Herald. This version is complete through the end of 2012.

ASTEROID LIGHTCURVE DERIVED DATA V13.0

This is a compilation of published rotational parameters derived from lightcurve data for asteroids, based on the Warner et al. (2009) Asteroid Lightcurve Database. This is the version released in March 2012. In addition to reported rotational parameters by individual paper, there is a summary file with the values adopted by Harris, Warner, and Pravec as the most likely correct values for each asteroid. The data set also contains files listing known binary asteroids and 'tumbling' asteroids.

Gartrelle et al. IRTF Asteroid Spectra V1.0

This data set is comprised of the VNIR (0.69-2.5 micron) spectra of twenty-five D-type asteroids from varying Solar System locations. The spectra were obtained from NASA/IRTF on Mauna Kea between 2016-2019 using the SpeX instrument in Low-Resolution Prism mode and the 0.8 x 15" slit. Guiding was performed using spillover light from the slit (GuideDog) for targets with apparent magnitude > 15.5. For targets fainter than magnitude 15.5, guiding was accomplished using the MORIS CCD imager.

TORINO ASTEROID POLARIMETRY

This data set contains asteroid polarimetric observations made during 1995-2005 with the Torino photopolarimeter at the 2.15-m telescope at El Leoncito Observatory in Argentina. These observations are reported in Cellino et al. (2005).

ASTEROID OCCULTATIONS V1.0

This data set is a collection of reported timings of observed asteroid occultations though 1998, and reliable occultation diameters published through the given STOP TIME. The timing data are previously unpublished; the diameters are reproduced from Millis and Dunham (1989) and Dunham, et al. (2002).

ASTEROID POLARIMETRIC DATABASE V1.0

The Asteroid Polarimetric Database (APD) is compiled by Dmitrij Lupishko of Kharkov University. This database tabulates the original data comprising degree of polarization as a function of phase angle of the asteroid, and additional parameters where available. This data set, together with 'polar.tab' containing the TRIAD polarimetry, includes most if not all existing asteroid polarimetry data published by 1995. The APD is an ongoing compilation and this data set will be updated yearly.
