Description

This data set is an aggregation of 27 PDS data sets with tabulations and compilations of asteroid data on CD-WO. The last update to data on this CD was made in January 1999. Apart from the fact that all the datasets are concerned with asteroid observations and measurements, the catalogs included here are not directly connected and should not be viewed as a coherent collection or volume of data. Note that this data set completely supercedes NSSDC data sets GD-11A, GD-11B, GD-11D and GD-11E. The data sets are (with PDS IDs listed in parentheses):

Asteroid Names and Discovery Circumstances V4.0

(EAR-A-5-DDR-ASTNAMES-DISCOVERY-V4.0) - This data set contains the names, designations, and discovery circumstances for all asteroids numbered as of the 1999 February 2 batch of Minor Planet Circulars, and includes 9999 entries sorted in order of catalog number. The data table includes fields for asteroid catalog number, name, principal provisional designation, discovery date, discovery location, and the name(s) of the discoverer(s). This data set supercedes past versions of both the ASTNAMES (Asteroid Names) and DISCOVER (Asteroid Discovery Circumstances) data sets. It represents an extension of a file originally prepared by Pilcher (1979) for the old Tucson Revised Index of Asteroid Data (TRIAD) and updated in Pilcher (1989) for the Asteroids II database. The data for asteroids numbered 4045 and higher were either provided by the Minor Planet Center or extracted from the Minor Planet Circulars, which are published by the Minor Planet Center on behalf of Commission 20 of the International Astronomical Union.

Asteroid Absolute Magnitudes V4.0

Observations which have not yet been published, or which have been reported only in an abstract, are included in the dataset as an entry with blank data fields, for the purpose of informing the dataset users of the existence of these detections. As the data from these detections are published, the data are added to this dataset in yearly updates. An entry for each detection reports radar cross-section, circular polarization, and radar albedo, if known, error values for these parameters, year of observation, and the reference in which the observations were reported.

The primary file is a FITS table of photometric measurements which contains the parameters given for each photometric observation including julian date of the observation, the observed magnitude, and the error value associated with the magnitude. The index to this primary file contains an entry for each asteroid lightcurve and refers to the individual photometric observations. Each entry identifies the asteroid, and specifies the filter used, the start and stop time of the lightcurve observation, the heliocentric distance, geocentric distance, phase angle, and geocentric ecliptic longitude and latitude of the asteroid at the time of the observation, the start byte and observation set size of the lightcurve, a code for the original published reference reporting the observations, and a code for each comment line.

The shape models consist of a grid of body centered latitude and longitude with a diameter listed for each grid point.

Asteroid Taxonomy V3.0

(EAR-A-5-DDR-TAXONOMY-V3.0) - This dataset provides asteroid taxonomic classifications of the Tholen, Barucci, Tedesco, Howell, and Xu et al. classification systems. Originally, only the reflectivities between 0.3 and 1.1 microns had been utilized for classification purposes, more recently, infrared data extending to 2.5 microns were used for the new Howell classification scheme. Taxonomic classifications have also been made on the basis of spectra, as in the Small Main-belt Asteroid Spectroscopic Survey (SMASS) of Xu et al. (1995). In this particular dataset, the four parameter fields indicate which parameters were used to arrive at the classification for the corresponding asteroid in each of the first four taxonomies. (The SMASS taxonomic classifications are all based on the SMASS spectra.)
