Reduced Photometer Data

Description

This data set, received from the experimenter, is contained on binary magnetic tapes written on a CDC 6600. Data cover only nighttime operation of the spacecraft, and each nighttime period covered includes complete spacecraft altitude, aspect, and ephemeris information along with relevant housekeeping information and the count rates of the six telescopes. The data from the individual telescopes are packed as 12-bit words, yielding a count rate range of from 0 to 4095. The third word of telescope 3 is incomplete, containing only 8 bits, and should not be used for detailed analysis. Questionable or missing data were set to 0. When turned off because of excessive light, the telescopes read a small number of counts (fewer than 20). For more information on this data set, contact Dr. Edward Ney, Astronomy Department, University of Minnesota, 116 Church Street SE, Minneapolis, MN 55455.
