The first should run line_2: in Week 1: the F439W exposure will be preflashed to line_3: ~50-80e level and the F675W will be preflashed to line_4: the ~200e level. In Week 2, the F439W image will be line_5: preflashed to the higher (~200e) level and the F675W line_6: will be preflashed at the lower (~50-80e) level. line_7: Note that the remaining exposures (F336W,F555W,F814W) line_8: will not be preflashed. ! !end of general form text general_form_address: lname: CLAMPIN fname: MARK category: PI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: (410) 338-4711 ! lname: MACKENTY fname: JOHN category: CI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: (410) 338-4559 ! lname: BAGGETT fname: SYLVIA mi: M category: CI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: (410) 338-5054 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC6752 descr_1: J,702 pos_1: RA = 19H 10M 08.24S +/- 0.1S, pos_2: DEC = -59D 50' 25.3" +/- 1.0" equinox: 2000 comment_1: NGC6752 IS THE ALTERNATE TARGET fluxnum_1: 1 fluxval_1: V=14.5 ! ! end of fixed targets !
