30-minute averaged count rates for all modes, ASCII


Availability: At NSSDC, Ready for Electronic Access

Time span: 1973-10-30 to 1980-03-11


This data set was created at NSSDC by converting 30-minute averaged count rates for all modes binary data set (SPHE-00089) to ASCII. Each record represents 30-min averages (48 averages for each of 13 channels per day, synchronized to 30-min intervals) and contains record type, year, day of year, orbit number, number of actual data items in the record (0~48), filter variables (for J1, J2, J3, J4), satellite ID (1 for IMP-7, 2 for IMP-8), half-hour of the century, 30-min averages for each channel, percentage of bad data during each average, and geocentric solar ecliptic coordinates.
