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.

SHAPE MODEL OF ASTEROID (153591) 2001 SN263 V1.0

We present the three-dimensional shapes and rotation states of the three components of near-Earth asteroid (153591) 2001 SN263 based on radar images and optical lightcurves (Becker et al., 2015. 2001 SN263 was observed in 2003 using the 12.6-cm radar at Arecibo Observatory. Optical lightcurves were obtained at several observatories and used to further constrain the shape modeling.

ASTEROID OCCULTATIONS V12.0

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 January 2014.

ASTEROID PHOTOMETRIC CATALOG V1.0

The Asteroid Photometric Catalog (3rd update), Lagerkvist, et.al., 1993 [LAGERKVISTETAL1993], is a compilation of all asteroid lightcurve photometry published up to and including the year 1992. The dataset includes the lightcurves in digital form and a table of references to all original publications.

WISNIEWSKI ASTEROID ABSOLUTE MAGNITUDES V1.0

Photometric observations of 125 asteroids, including absolute magnitudes, reported in Wisniewski et al. 1997.

24-COLOR ASTEROID SURVEY

This dataset is comprised of asteroid flux data measured in 26 filters using the McCord dual beam photometer, and covering the range 0.32 - 1.08 microns for 285 numbered asteroids, as published in Chapman & Gaffey (1979b) and McFadden, et al. (1984).

SMASS ASTEROID SURVEY V1.0

The Small Main-belt Asteroid Spectrographic Survey (SMASS) was initiated in 1990 with the goal of obtaining spectra over the visual wavelength region for a substantial number of small (D < 20 km) main-belt asteroids. Observations were primarily made using the 2.4 m Hiltner telescope, located at the Michigan-Dartmouth-MIT (MDM) Observatory on the southwest ridge of Kitt Peak in Arizona.

NEAR-INFRARED PHOTOMETRY OF ASTEROIDS FROM DENIS V1.0

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.

IRAS MINOR PLANET SURVEY ASTEROIDS V4.0

The data presented with this data set include: (a) 8210 individual sightings associated with 2004 asteroids, (b) averaged radiometric diameters and geometric albedos derived from individual observations for 1796 numbered asteroids and 88 unnumbered asteroids (as of 1983) whose orbital elements were determined using astrometry from two or more apparitions; (c) an entry for each of 120 asteroids for which there is an accepted sighting; (d) entries for each of 4677 numbered asteroids and 2632 unnumbered asteroids (as of 1985) for which associations were sought in the IRAS data; (e) A summary of the number of times each asteroid was predicted to be scanned, and possible reasons for any failure to be detected.

ASTEROID DYNAMICAL FAMILIES V2.0

This data set contains the Zappala et al. (1995) [ZAPPALAETAL1995] asteroid dynamical families classifications, based on the hierarchical clustering method applied to the proper elements of Milani & Knezevic (1994) [MILANI&KNEZEVIC1994]. It includes 12,487 numbered and unnumbered asteroids.

ASTEROID OCCULTATIONS V6.0

This data set is intended to include all reported timings of observed asteroid occultation events as well as asteroid occultation axes derived from those timings by David W. Dunham and David Herald. Some occultations by planetary satellites are also included. This version is complete through the end of 2007, and contains additional events from 2008.

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.

ASTEROID RADAR V6.0

This data set is intended to include all groundbased asteroid radar detections. These entries were collected by Steven J. Ostro, and selected data have been provided as collected from the published literature.

ASTEROID DYNAMICAL FAMILIES V3.0

This dataset contains the asteroid dynamical family classifications contained in Zappala, et al. (1995) [ZAPPALAETAL1995]. These are based on the heirarchical clustering method applied to the proper elements of Milani and Knezevic (1994) [MILANI&KNEZEVIC1994]. 12,487 asteroids, numbered and unnumbered, are included.

POLARIMETRY OF ASTEROID ITOKAWA V1.0

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).

NESVORNY HCM ASTEROID FAMILIES V1.0

This data set contains asteroid dynamical family memberships for 55 families, calculated by David Nesvorny using his code based on the Hierarchical Clustering Method (HCM) described in Zappala et al. (1990, 1994). The input proper elements for 293,368 asteroids were calculated by Milani and Knezevic and are restricted to low-inclination asteroids.
