Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information. The associated data file is: The data in the associated file were obtained by the UVS instrument during the Jupiter Orbit Operations mission phase. The geometry data in the referenced file was created with the UVS observation visualization program called GGGS (Galileo Geometry and Graphics Software). The menu item 'Observation FOV Table' creates a table of geometry values for the UVS instrument boresight. The UVS F and G/N-channel field-of-view (FOV) boresights are coincident. The time of the first value in the geometry table corresponds to exactly the time of the first record in the data file. Subsequent entries in the geometry table are exactly one RIM after the preceeding table entry. Since no time values are given in this file, the label time values are extracted from the data file label and may represent more time than the geometry table actually contains. The GGGS program calculates the boresight values from SPICE kernels covering the observation period. No log of the kernels used has been kept. Generally, kernels were final pointing kernels. Ocssionally, comments will indicate the SPICE source. The geometry parameters are specified in one of the Header lines. Values are free-format ASCII, space delimited, in System III and planetocentric. The associated data file is described in its' label. Comments may appear in the right-hand column area. Generally the included parameters are: FOV (index number, one per RIM), PLANETOCENTRIC LATITUDE (DEGREES), PLANETOCENTRIC SYSTEM III LONGITUDE (DEGREES), SOLAR INCIDENCE ANGLE (DEGREES), PHASE ANGLE (DEGREES), EMISSION ANGLE (DEGREES), COSINE EMISSION ANGLE (Mu), COSINE INCIDENCE ANGLE (Mu0), ALTITUDE (KM) above tangent normal for non-intersecting FOV boresight, or distance to body for intersecting boresight (may not be given). A sample of the geometry table for the orbit C20 Callisto observation of Bran crater is given below. The corresponding data is located in data file: C20A_UPB_BRANCR01.DAT .
