The data file is a binary, fixed record length file, and the header is an ASCII file. All of the Cassini MAG flatfiles represent time as a spacecraft clock value, referenced to 1958, with the minor frame converted from units of 1/256 sec to units of milliseconds. This label provides a mapping between the internal time representation (NATIVE_START_TIME), true spacecraft clock (SPACECRAFT_CLOCK_START_COUNT) and spacecraft event time in UTC (START_TIME). 5 0 24 TIME_TAI 1 1 IEEE754MSBDouble 8 Second Time is represented as SCET in seconds since the epoch Jan 1 2000 12:00:00 TAI (= 11:59:28 UTC) .

This header is used to read the data file by a variety of software packages developed at UCLA. Other users of the data may ignore this file. 0 7-Bit ASCII Text Line-Feed
