Hourly Averaged Count Rate Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1973-10-28 to 1990-12-31


These electron, proton, and He isotope count rate data were supplied by the experimenter on binary magnetic tape. The data were created on an IBM 370/158 computer with a block size of 520 bytes. One record was written for each hour, and records are grouped into files of 10 days in length to facilitate searching for a particular date. Records written for hours in which no data were available are flagged by negative identification fields. Files with no data have only one record. The count rates given are described in the experimenter-supplied format.
