Data Set Overview
=================
This data set contains 81 published spectra of asteroids
obtained by Faith Vilas during the years 1982 - 1992. These
appeared in the following papers:
Vilas et al. 1985, Icarus 63, 201. [VILASETAL1985]
Vilas and Smith 1985, Icarus 64, 503. [VILAS&SMITH1985]
Vilas and McFadden 1992, Icarus 100, 85. [VILAS&MCFADDEN1992]
Vilas et al. 1993a, Icarus 102, 225. [VILASETAL1993A]
Vilas et al. 1993b, Icarus 105, 67. [VILASETAL1993B]
Modification History
====================
This data set first entered the PDS archives following its
successful external peer review on 23 March 1998.
Parameters
==========
Each spectrum is contained in a separate file, and lists wavelength,
reflectance and error. The index file for this collection contains
observation dates, visual magnitude, integration time, phase angle,
solar elongation, geo- and heliocentric distances, airmass,
wavelength coverage limits, normalization wavelength and solar
analog stars for each spectrum included. An additional files lists
identification(s), visual magnitude, spectral type, position, and
Hardorp class for each of the solar analog stars referred to in the
spectrum files.
Processing
==========
The details of the data processing are reported in the individual
papers.
