Voyager Mission Dictionary 1.0.0.0 Mission Matthew Tiscareno rings vgr v0.1.0.0 2022-06-10 Created by unifying the vg1 and vg2 namespace dictionaries, which will be deprecated. Specifically, the new base class Voyager contains the legacy label (optional), a class describing telemetry (also optional), a class describing timing (required), and a required class describing instrument-specific parameters (currently, only ISS is implemented). This is a preliminary non-release version. Changes have not been tracked during initial drafting, but will be henceforth. v0.2.0.0 2022-08-23 Continuing to develop content, in advance of any use of this LDD. Updated enumerated values for compression_state, edit_mode_id Deleted beam, companding, elec_cal, exposure_type, filter_position, filter_step, flood, g1_voltage_count, geometry_state, image_time, image_type, pixel_dn_average_thresh, pixel_dn_average_status, shutter_exposure, shutter_reset, shutter_open, shutter_close, start_time_doy, start_time_ymd, stop_time_doy, stop_time_ymd, telemetry_mode Deleted classes Image_Description, Image_State, and Instrument_State. The attributes that were in Image_Description and Image_State are now in the previous parent class ISS, while the attributes that were in Instrument_State have all been deleted per the line above. Renamed data_anomaly_type to pds_source_product_data_anomaly_type Made some attributes nillable or optional v0.3.0.0 2022-09-20 Continuing to develop content, in advance of any use of this LDD. Restored many of the attributes removed in v0.2, while prepending "legacy_label_" to the attribute names and adding class ISS_Legacy_Label to contain them. Also moved some attributes from class ISS to class ISS_Legacy_Label, again now prepending those attribute names with "legacy_label_". v0.3.1.0 2023-03-09 Added enumerated value "Manual" to legacy_label_na_exposure_type and legacy_label_wa_exposure_type. v0.4.0.0 2023-04-18 Updated definitions and patterns for fds_scet_epoch_1, fds_scet_epoch_2, fds_scet_epoch_3, and fds_scet_epoch_4. Updated definition and nillable_flag for spacecraft_clock_count_partition. Updated definitions for spacecraft_clock_start_count and spacecraft_clock_stop_count. Added an enumerated value for edit_mode_id. v0.5.0.0 2023-07-17 Updated definitions for spacecraft_clock_start_count and spacecraft_clock_stop_count. Updated value_data_type and removed pattern for fds_scet_epoch_1, fds_scet_epoch_2, fds_scet_epoch_3, fds_scet_epoch_4, and spacecraft_clock_count_partition. Updated nillable_flag for earth_received_time. Added enumerated values for edit_mode_id, legacy_label_na_exposure_type, and legacy_label_wa_exposure_type. v0.6.0.0 2023-07-19 Updated value_data_type for edr_tape_id.

This attribute corresponds to the keyword FILTER_NAME in earlier versions of Voyager data products.

The clock count is always a seven digit value, five digits to the left of the decimal point and two digits to the right of the decimal point. This attribute corresponds to the keyword IMAGE_NUMBER in earlier versions of Voyager data products. false ASCII_Real legacy_label_lsb_truncate 1.0 legacy_label_lsb_truncate false Matthew Tiscareno Whether the LSB Truncation mode was operating. Documentation is unclear, but it seems likely that this mode involved either regular rounding (truncating the least significant bits), or keeping only a certain number of the least significant bits while the bits corresponding to larger place values are truncated. This attribute preserves information found in Line 11 of the VICAR-1 legacy header (for more information, see the attribute definition for legacy_label_VICAR1).

This attribute, while required, is nillable. A nil_reason of missing indicates that it was missing from the source product, which in turn implies no anomalies were detected. In the source product, DATA_ANOMALY_TYPE = RAM_DATA_CORRUPTION indicates that spurious values exist in the image data due to corruption of the random access memory onboard the spacecraft.

Voyager used the term Flight Data System (FDS) for this quantity, which is equivalent to the term spacecraft clock (SCLK) more commonly used by subsequent missions. The format is n/sssss:dd:mmm where n is the partition (0 if unknown), sssss is the FDS count (48 minutes per count for sssss), dd is units of 1/60 an FDS count (that is, 48 seconds per count for dd), and mmm is an optional fraction of dd (unused and value unknown). Note: Since the mmm digits are optional, it is possible (and may be common) for spacecraft_clock_start_count to be identical to spacecraft_clock_stop_count for exposure_duration values less than 48 seconds.
