DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set includes 3-micron spectra of asteroids taken by Andy Rivkin (1995) [RIVKINETAL1995]. The spectra include both measured reflectance and error bars at six points in the range 1.25-3.35 microns. 17 spectra of 16 different asteroids are included. One asteroid, 77 Frigga, is included in this data set but was not mentioned in Rivkin, et al. (1995). Modification History : This dataset was first ingested into the PDS archives following the March 1998 asteroid data sets review. In March 2002 the data were re-examined as part of a general review of holdings. As a result, the following changes were made: o The data from tables I ('Targets Observed') and II ('Observational Circumstances') of Rivkin, et al. (1995) were incorporated into the main data file. o The main data file was split into (additional) separate files for each object. The data for the 1991 and 1993 observations of 44 Nysa were placed in separate files. o As much information as could be gleaned from the published article was used to create the instrument catalog file now archived with this data. PDS cataloging fields have been filled in as far as possible. o This data set catalog file was updated to contain the modification list and the complete list of specific target names for objects observed. Parameters : The data table lists asteroid number, a spectrum identifier, and the measured reflectance and one-standard-deviation error at 1.25, 1.65, 2.20, 2.95, 3.12 and 3.35 microns.
