Instrument Overview
===================

The instrument operates from 0.62 to 2.5 micrometers, with a spectral
resolution of 1.5 percent (delta lambda/lambda).  The system used a two 
section circular variable filter (CVF) and a single indium antimonide 
detector, both cooled with liquid nitrogen.  There are 120 channels of data.
The first half of the CVF produces data at a spectral resolution of ~100
Angstroms while resolution of the second half is ~200 Angstroms. The full
spectral range was scanned and recorded every few minutes during 
observations at the 2.2 m telescope on Mauna Kea.  Multiple scans, or 
'runs', were obtained for each object. See McCord, et al., 1981 
[MCCORDETAL1981] and Pieters and Pratt, 2000 [PIETERSANDPRATT2000]
for details."
