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. Also see the UVS instrument template. It may also be useful to compare the UVS pointing geometry files to the EUV pointing geometry files. For explicit Footprint parameter definitions, see the long description in the label format file: uvs_footprint.fmt All Footprint values and reference locations are DOUBLE PRECISION values ( eight byte floating point values ). Each record contains 180 elements. Files generated on the unix machine (those with the '.foot' file extension) are accessed in IDL with the Fortran 77 unformated option. For example: IDL> close,1 & openr,1,'j0cd_urt_g1aura12.dat', /f77_unformatted IDL> a=dblarr(180) & readu,1,a The unix footprint data files were generated in 2007 using the original Vax footprint source code modified to execute on the unix platform. The source code is /ansa4/gllsoft/foot/src/spice_foot. The target bodies of the observations are referenced above in the 'log'. During calibrations and instrument test, the target body is Jupiter although the actual target may have been a star. See the OAPEL file. The UVS field of view is defined by 9 vectors and viewing data for each vector is contained in the footprint. The field of view vector definition can be found in the UVS SPICE I kernel. This I kernel is currently located in: /vixen2/ggs/Kernels/Constants/gll34001.ti. (When reviewing this file for the size of the FOV used, be sure to look at the data statements toward the end of the file, and not at the diagrams, for the true value used by the SPICE routines.) ............................................................."
