A Directory containing Daily FTP downloadable Files containing Readout-by-Readout Listings of HET Housekeeping Parameters (Voltages, Temperatures, Offsets). The Naming Convention of the Files is uly_het_full_house_YYYDDD.txt, where YYY indicates the three digit Year since 1900 (e.g. YYY=090 for 1990, and YYY=102 for 2002) and DDD indicates the three digit Day of Year (January 1 = 1). In each File, following a detailed Description of the Format, the Data consist of a Listing of HET Housekeeping Parameters measured at the Time listed in the first four Columns of each Line. Each Line contains Data for one Readout of the Parameters. The first four Columns give the Time of the Measurement as Fractional Year (to 12 Decimal Places) and as Year since 1900, Day of Year, and Milliseconds of Day. At the most common Science Telemetry Rate, 2048 bps, each Parameter in this File is Readout once every 256 s. The Measurements are instantaneous, and do not represent an Average of Values over the Interval since the last Readout. The sole Function of these Parameters is to monitor Instrument Health. No Noise Removal or Despiking has been done, so Caution must be used in interpreting isolated large Increases or Decreases in the measured Parameters.

The User Notes File at the Ulysses Final Archive (UFA) describes the Format of the ASCII Data Files for the COSPIN High Energy Telescope, HET
Top Level Descriptions of Formats and Contents of the six File Types that make up the COSPIN HET Full Resolution Data Set. Detailed Descriptions of the Formats and Contents are found in Header Lines at the Start of each downloaded Data File. The Data covered by this SPASE Description are described in the ReadMe under the Heading House. (*** Note ***: During the Build-up of this Data Set, a few Errors and Omissions have been found in the Header Lines for some of the File Types. These Errors and Omissions are listed in this ReadMe File. Upon Completion of the Data Set, all Errors and Omissions discovered will be corrected in all of the Header Lines of all of the File Types at which time this Note will be removed).
