Tiscareno 2019 metadata This table describes the general properties of each Cassini VIMS cube. 2019-08-03 1.0 Initial delivery index.tab 2020-03-29T06:02:10 472402899 400681 b4a8c9e5b166caa29e3590e03951a225 This table describes the general properties of each Cassini VIMS cube. 0 400681 This Cassini VIMS image index has been adapted by the PDS Ring-Moon Systems Node for the PDS4 version of the data set. This file was obtained from the RMS Node website at this URL: https://pds-rings.seti.org/viewmaster/metadata/COVIMS_0xxx/COVIMS_0999/COVIMS_0999_index.tab It was downloaded on July 30, 2019. Two additional, leading columns, containing the image LID and PDS4 raw image file path, have been pre-pended to each record; the remainder of each record is unchanged. For cases in which multiple versions of the same VIMS cube are provided in this bundle, metadata is only provided for the latest version. Following is the description field of the file as originally downloaded. This version of the Cassini VIMS image index has been edited by the PDS Ring-Moon Systems Node for compliance with PDS3 standards. Invalid rows have been edited so they obey the specified DATA_TYPE and can therefore be read more easily by software. For example, where a numeric column contained '*****', that value has been replaced by '-1.E32' and, in the label, a numeric value of -1.E32 has been identified as the NULL_CONSTANT or NOT_APPLICABLE_CONSTANT. In addition, PDS3 syntax errors have been corrected in this label. Note that NULL_CONSTANT identifies values that could be known but are not, whereas NOT_APPLICABLE_CONSTANT refers to values that are undefined. An example of the former would be a missing value of SC_SUN_POSITION_VECTOR; an example of the latter would be a value of LOWER_LEFT_LATITUDE in an image where the lower left corner does not intercept the target body.

STOP_TIME 7 188 ASCII_Date_Time_YMD 23 Spacecraft Event Time (SCET) of the VIMS IR shutter closing in the format YYYY-MM-DDThh:mm:ss.[fff], where YYYY is the year, MM is the month, DD is the day, hh is the hour, mm is the minutes, and ss.[fff] are the seconds. SPACECRAFT_CLOCK_START_COUNT 8 213 ASCII_String 20 Spacecraft clock start count reading of the VIMS IR shutter opening. SPACECRAFT_CLOCK_STOP_COUNT 9 236 ASCII_String 20 Spacecraft clock stop count reading of the VIMS IR shutter closing. TARGET_NAME 10 259 ASCII_String 30 The target name identifies the primary target of the observation. INSTRUMENT_MODE_ID 11 292 ASCII_String 20 The mode in which the instrument is acquiring data, most commonly IMAGE but also LINE, POINT, OCCULTATION, CAL_SOLAR, CAL_SPECTRAL, CAL_BACKGROUND, or CAL_ELECTRIC. OBSERVATION_ID 12 315 ASCII_String 30 A string that consists of the instrument, the orbit number, the target code, a description of the observation, and instance number. For example, VIMS_000PH_PHOEBE031 is data of PHOEBE taken by VIMS during orbit 000. SPECTRAL_EDITING 13 348 ASCII_String 3 Indicates whether this cube has been reduced to a subset of the bands in the original cube. If 'OFF', none of the original bands of the cube were intentionally omitted. See BAND_BIN_ORIGINAL_BAND to determine which bands are present. SPECTRAL_SUMMING 14 354 ASCII_String 3 Indicates whether this cube has had some bands summed to reduce the SSR data volume. See BAND_BIN_ORIGINAL_BAND to determine which bands have been summed. STAR_TRACKING 15 360 ASCII_String 3 Normally, the VIMS field of view is changed by altering the size (SWATH_WIDTH and SWATH_LENGTH) of the subset of the array and by changing the position of that subset (X_OFFSET and Z_OFFSET) within the array. This is the default, when STAR_TRACKING is OFF. When STAR_TRACKING is ON, the tracking is accomplished by causing the instrument to ignore the supplied X and Z offsets in the instrument setup, and instead track the brightest pixel in the array as it moves over time. The brightest pixel is set in the instrument by running a previous instrument setup (of a minimal size), which will cause the X and Z position of the brightest pixel to be automatically set inside the instrument. This position is then used as the initial brightest pixel, and it will be tracked over the life of this setup. SWATH_WIDTH 16 365 ASCII_Integer 2 The number of pixels (in the X direction) collected during an observation. This will differ from CORE_ITEMS (1) for Occultation Mode cubes. The angular size of these pixels is dependent upon the resolution mode selected. SWATH_LENGTH 17 368 ASCII_Integer 2 The number of slices (in the Z direction) collected during an observation. This will differ from CORE_ITEMS (3) for all packed cubes and Occultation Mode cubes. The angular size of these lines is dependent upon the resolution mode selected. IR_EXPOSURE 18 371 ASCII_Real 10 The IR exposure time for each pixel, in milliseconds. -999. IR_SAMPLING_MODE_ID 19 383 ASCII_String 8 The spatial resolution mode of the IR channel. Either NORMAL for 0.5 mrad x 0.5 mrad pixels, or UNDER for NYQUIST sampling (0.5 x 0.5 mrad), or HI-RES for 0.25 x 0.50 mrad sampling. VIS_EXPOSURE 20 393 ASCII_Real 10 The VIS exposure time for each line, in milliseconds. -999. VIS_SAMPLING_MODE_ID 21 405 ASCII_String 8 The spatial resolution mode of the VIS channel. Either NORMAL for 0.5 mrad x 0.5 mrad pixels, or HI-RES sampling (0.167 x 0.167 mrad), or N/A if the VIS channel is OFF. PRODUCT_ID 22 416 ASCII_String 22 A permanent, unique identifier assigned to a data product by its producer. The product id is the sclk string that represents the spacecraft time at the moment that the data was taken. The SCLK string is a spacecraft timing partion (usually 1) followed by a forward slash followed by the spacecraft clock value (an integer representing the amount of time since the spacecraft partition became active.
