How to use the Radiation Model Program The program diskh:[gllseq.software]background_rad_model.pro uses spice kernels to estimate the background radition levels during uvs observations. The output file of this program lists the following: (1) event-- observation command or voltage commmand (hv, f, n ,g) (2) time-- The time of the event (3) Rj-- The distance of Galileo from Jupiter (4) Radiation-- The background radiation in count/sec (5) Radiation dosage-- The dosage in counts (6) Object-- The object being observed (7) Observation Name-- The name of the observation At the end of the data file, the observation times are totaled in rims and hours. The total radition dosage in counts is given for each tube during the given orbit, separating objects from torus observations. This list file is kept on line in diskk:[orbit_design.*.sef_products], where the * represents the orbit (i.e. g1). The file is name radiation_model_*.lis. To run the program, type check. The second program, diskh:[gllseq.software]Jupiter_rad_model.pro reads the output file from the the above file and adds in the counts from Jupiter sun-lit observations. To run the program, type check2. This program will ask for the time that the viewed object was sun-lit and the percentage of the field of view the object covers. This information must be found by gggs plots. This program will also ask if any observations were not asked about, such as a NIMS ride along.
