The images will appear symmetrical and should be line_3: close to focus in all four cameras. It'll possibly correct line_4: any position of the pick-off mirror if needed and provide line_5: an aperture location update for the PDB. It'll also line_6: provide initial verification of AFM stability and operation line_7: over periods of several orbits. ! ! end of abstract general_form_proposers: lname: BURROWS fname: CHRIS inst: ST SCI country: USA esa: Y ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: This part of the WFPC2 alignment and will only be performed if line_2: needed. ! question: 3 section: 1 line_1: The repeated image of a fairly crowded and bright field in line_2: WFALL takes 5 seconds in F555W. There are mV=14-15 stars line_3: near the center of all chips (about 12 total in the field.) line_4: These stars are exposed to predicted half to full well with line_5: gain 15 e/DN. This basic exposure is then taken repeatedly line_6: with the fold mirrors moved in a outward spiralling 4x4 pattern line_7: centered at the position determined by proposal 4270 (WFPC2 line_8: Coarse Focus/ WFII-ALI-02). The center position itself is line_9: is taken twice - once at the beginning and once at the end of line_10: the sequence. The scan steps are each about 48 arcsec line_11: corresponding to about 61 command voltage steps, and to a line_12: 1.1% pupil shear of 1/12.7 waves rms coma, giving a total line_13: coverage of +/- 72 voltage steps from the starting point. The line_14: time for each set of mirror adjustments can be kept to under line_15: 6 minutes when the commanding is interleaved (a single line_16: adjustment takes 5 min 19 sec). The first four sets of line_17: positions, together with the central position are repeated line_18: at the end with a different set of guide stars thus providing line_19: the best coverage in the central region and protecting against line_20: an initial attitude update problem (or guide star acquisition line_21: failure), for example. This repeat can be scheduled a day line_22: or sl later in case the tape recorder is filled by the first line_23: set of exposures. Two targets are used from proposal 4333 (WFPC2 ! question: 3 section: 2 line_1: Coarse POM Adjustment, Act Sum WFII-ALI-02). We also need line_2: 3 five second dark exposures at the beginning of the proposal. ! question: 5 section: 1 line_1: Prerequisites: line_3: 1) Proposal 4270 ( WF/PC-II Coarse Focus -- line_4: Act Summ WFII-ALI-03) must be completed prior to line_5: execution of this proposal. line_6: 2) Proposal 5252 (WF/PC-II AFM Turn on -- Act Summ line_7: WFII-05). line_8: 3) The Secondary Mirror Move #2 and COSTAR DOB Adjustments line_9: may need to be completed. (This is in proposal 4270) line_10: 4) CCDs at -22C or lower (Proposal 4721). line_11: 5) TEC power can be off. line_13: Scheduling Request: line_15: Please use a different set of guide stars for lines line_16: 206-241. ! !end of general form text general_form_address: lname: BURROWS fname: CHRIS category: PI inst: ST SCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 410-338-4913 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC188 descr_1: J,704 pos_1: RA=00H 42M 10.9S +/- 0.0044S, pos_2: DEC=+84D 59' 43.3" +/- 0.0058S equinox: 1950 fluxnum_1: 1 fluxval_1: V = 15.00 +/- 0.1 fluxnum_2: 1 fluxval_2: B-V = 0.0 +/- 0.1 ! ! end of fixed targets !
