This data set, supplied by the principal investigator, contains experiment directory data on a binary magnetic tape written on an IBM 360 computer. The tape contains several formats and are made up from selected records from data tapes and from attitude-orbit (AO) records. The tape gives experiment operating times and identify when the sensor was looking upward and downward. Format statements are provided for (1) AO records, which include various orbit parameters such as the Greenwich mean time (in milliseconds of day) for orbit start and end, and for eclipse start and end; (2) selected minute and special event AO records, which include the Greenwich mean time of measurements (in milliseconds of day), latitude and longitude, sun-earth-satellite angle, magnetic latitude, McIlwain's L-shell parameter, ecliptic and galactic latitude and longitude; (3) label records, which include tape and file identification; (4) minute summary records, which include tape labels, average experiment temperature, minimum and maximum scan angles, and number of seconds for each mirror position and for dark current; and (5) file summary records, which include start and stop times in milliseconds of day, total number of samples, and total number of seconds of photocurrent measurement in each mirror position. This data set was used to generate the microfilm data set 67-073A-12G.
