A Directory containing Daily FTP downloadable Files containing Readout-by-Readout Listings of the Counts accumulated in the H1-H9 Spin-Averaged Counting Rates. These Counting Rates respond primarily to Protons (H1-H5, H9) in the approximate Energy Ranges 5.4-14, 14-19, 24-31, 34-68, 68-92, and >92 MeV, respectively, and to Electrons (H6-8) in the very approximate Energy Ranges 1-3, 5-10, and 3-5 MeV, respectively. The Naming Convention for the Daily Files is uly_het_full_rat_omni1_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 Counts accumulated in the H1-H9 Spin-Averaged Counting Rates during the Intervals between successive Readouts, organized into Columns as described below. The first four Columns give the Start Time of the Counting Rate Accumulation Period as Fractional Year (to 12 Decimal Places) and as Year since 1900, Day of Year, and Milliseconds of Day at the Start of the Accumulation, followed by one Column giving the Duration of the Accumulation Period in Milliseconds (it is the same for all nine Rates), and nine Columns giving the Counts accumulated in that Period for each Rate. All Fields except for the Fractional Year are in Integer Format. Each Line contains Data for one single Readout of the Rates H1-H9, and all Readouts where at least one of the Rates has a Non-fill Value are included. Where Fill does occur it is indicated by -1. Since the Accumulation Period for each Readout is forced to include an Integral Number of Spacecraft Spins in order to produce pure Spin-Averaged Measurements, the Lengths of the Accumulation Periods vary in a Cyclic Manner as the Period of the Telemetry Cycle beats with the Spacecraft Spin Period. All Counting Rates in this File are read out twice per Spacecraft Format. At the most common Science Telemetry Bit Rate (2048 bps) this corresponds to an Average Interval between Readouts of 16 s. Thus, with a typical 5 rpm Spacecraft Spin Rate the Accumulation Intervals vary in a repeating Cycle of 12, 12, 24, 12, 12, 24, 12, etc., seconds. At lower Bit Rates the Average Interval is equal to 16 times (2048/BR) seconds and the Cycle automatically adjusts to produce this Average Accumulation. No Noise Removal or Despiking has been done, so Caution must be used in interpreting isolated large Increases or Decreases in the Counting Rates.

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 omni1. (*** 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).

Length of the Accumulation Period
Counts accumulated by Counting Rate H1 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H1 Counting Rate normally responds primarily to Protons in the Energy Interval 5.4-14 MeV (Normal Incidence).
Counts accumulated by Counting Rate H2 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H2 Counting Rate normally responds primarily to Protons in the Energy Interval 14-19 MeV (Normal Incidence).
Counts accumulated by Counting Rate H3 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H3 Counting Rate normally responds primarily to Protons in the Energy Interval 24-31 MeV (Normal Incidence).
Counts accumulated by Counting Rate H4 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H4 Counting Rate normally responds primarily to Protons in the Energy Interval 34-68 MeV (Normal Incidence).
Counts accumulated by Counting Rate H5 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H5 Counting Rate normally responds primarily to Protons in the Energy Interval 68-92 MeV (Normal Incidence).
Counts accumulated by Counting Rate H6 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H6 Counting Rate normally responds primarily to Electrons in the Energy Interval from about 1-3 MeV (Normal Incidence). This Counting Rate discriminates strongly against Nuclei by requiring Anti-Coincidence with a Discriminator set slightly slightly above the Energy deposited by Minimum Ionizing Particles in D1, but below the Minimum Energy deposited by a Proton stopping in D2.
Counts accumulated by Counting Rate H7 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H7 Counting Rate normally responds primarily to Electrons in the Energy Interval from about 5-10 MeV (Normal Incidence). This Counting Rate discriminates strongly against Nuclei by requiring Anti-Coincidence with Discriminators set above the Energy deposited by Minimum Ionizing Particles, but below the Minimum Energy deposited by a Proton stopping in the Telescope.
Counts accumulated by Counting Rate H8 during the Period of Coverage (Column 5) starting at the Time defined in Columns 1-4. The H8 Counting Rate normally responds primarily to Electrons in the Energy Interval from about 3-5 MeV (Normal Incidence). This Counting Rate discriminates strongly against Nuclei by requiring Anti-Coincidence with Discriminators set above the Energy deposited by Minimum Ionizing Particles, but below the Minimum Energy deposited by a Proton stopping in the Telescope.
Counts accumulated by Counting Rate H9 during the Period of Coverage (Column 5) Starting at the Time defined in Columns 1-4. The H9 Counting Rate normally responds primarily to Protons with Energies greater than about 92 MeV, which completely penetrate the Telescope Detector Stack. Thus it provides a Measure of the Integral Intensity of Energetic Charged Particles with Penetrating Power equal or greater to that of 92 MeV Protons.
