This is complementary to line_3: the individual SI aperture calibrations, and checks line_4: the relative distances between TA apertures, while line_5: at the same time checking on the accuracy of Mode 1 line_6: WFPC-assisted target acquisitions. The program's aim is line_7: accomplished by maneuvering between instruments and line_8: by determining the errors using Mode 2 (onboard) TAs. line_9: Due to the power limitations of HST, only 2 SI's line_10: (plus WFPC) can be checked at each visit. The sequence line_11: of observations is the following: line_13: 1. PC image of an astromertic standard (in omega Cen) line_14: 2. slew to SI 1, image of TA aperture line_15: 3. (optional) parallel PC image line_16: 4. Mode 2 target acquisition line_17: 5. slew to SI 2, image of TA aperture line_18: 6. (optional) parallel PC image line_19: 7. Mode 2 target acquisition line_21: To assess the accuracy of maneuvering, the engeneering line_22: data have to be analysed as well, but no requirement line_23: is necessary on transmission speed ! question: 3 section: 1 line_1: The program must be split in several portions, since line_2: it is not possible to check all intruments at once. line_4: As first priority, FOS and GHRS should be tested (once line_5: a month the first 6 months - to check for short term line_6: variations -, then every two months). HSP calibration line_7: probably depends on need, but FOC should be calibrated line_8: as well, especially in case FOC-assited target line_9: acquisitions become necessary. ! question: 6 section: 1 line_1: To simplify the execution of this program, it would line_2: be extremely convenient to perform it immediately line_3: after the WFPC photometric-astrometric calibration line_4: program (2877), which uses essentially the same field line_5: and would save at least 20 minutes per visit of line_6: spacecraft time. ! !end of general form text general_form_address: lname: GILMOZZI fname: ROBERTO category: PI inst: ST SCI ! lname: ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: OMEGA-CEN2213 descr_1: CALIBRATION STAR pos_1: RA = 13H 25M 41.13S +/- 0.05S, pos_2: DEC = -47D 34' 24.7" +/- 0.2" equinox: 1950 pm_or_par: N fluxnum_1: 1 fluxval_1: V = 14.71 +/- 0.03 fluxnum_2: 2 fluxval_2: B-V = 0.17 +/- 0.03 ! ! end of fixed targets !
