Abstract

The data collection system for the MASCOT (MIT Astronomical Spectrometer/ Camera for Optical Telescopes) is described. The system relies on an RCA 1802 microprocessor-based controller, which serves to collect and format data, to present data to a scan converter, and to operate a device communication bus. A NOVA minicomputer is used to record and recall frame images and to perform refined image processing. The RCA 1802 also provides instrument mode control for the MASCOT. Commands are issued using STOIC, a FORTH-like language. Sufficient flexibility has been provided so that a variety of CCDs can be accomodated. At present, Texas Instruments virtual phase CCDs are utilized. This is the second of two papers describing the MASCOT.
