SEVEN COLOR ASTEROID SURVEY V1.0

The Seven-color Asteroid Survey (SCAS) was conducted at the IRTF on Mauna Kea, Hawaii from 1992 to 1994. It consists of photometry in seven filters from 0.9 to 2.3 microns, lettered A through G in order of increasing wavelength. The bandpasses were specifically designed to capture the essential mineralogic information present in infrared asteroid spectra. The filter bandpasses were chosen to avoid the atmospheric water features at 1.4 and 1.9 microns.
