description
12210_MRDCD_HKANAN is an IGPP Flatfile which consists of two files: a data file (.FFD) and a header file (.FFH). 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). See the collection description file (data-hk-ana-hkrate-desc.txt) and the MAG volume SIS (VOLSIS.PDF) for additional information on the MAG time tag. The analog housekeeping data file contains the following columns: Name Units Description ================================================================= SCLK(1958) Counts Time (sclk NOT UTC) is represented as decimal seconds relative to the epoch Jan 1 1958 00:00:00.000. PreampOut Volts Subcommutated VHM data - pre-amplifier output. IRDectBias Volts Subcommutated VHM data - infrared detector bias. HeLmpRFAmp Volts Subcommutated VHM data - He lamp RF amplifier. HeCllRFAmp Volts Subcommutated VHM data - He cell RF amplifier. BIU VCCSPV Volts Subcommutated VHM data - BIU VCC, BIU supply voltage. +/-3.75V Volts Subcommutated VHM data - +/-3.75 V supply. +/-12V Volts Subcommutated VHM data - +/-12 V supply. +/-6.2V Volts Subcommutated VHM data - +/-6.2 V supply. VCOMonitor Volts Subcommutated SHM data - VCO (Voltage Controlled Oscillator) monitor. +/-7V Volts Subcommutated SHM data - +/-7V supply. Detect2fg Volts Subcommutated SHM data - Detected 2fo. VCOModltn Volts Subcommutated SHM data - VCO modulation. +7.5V Volts Subcommutated FGM data - +7.5V supply. -7.5V Volts Subcommutated FGM data - -7.5V supply. Field(3) Volts Subcommutated FGM data - X, Y, and Z component of magnetic field respectively. PSU (2) Volts Subcommutated FGM data - Power Supply Unit 1 and 2 respectively. Ground F Volts Subcommutated FGM data - FGM Ground. Reference Volts Subcommutated DPU data - Reference voltage. =================================================================
