This proposal describes the procedures for f/48, f/96, line_3: and f/288. The procedure is based on 5 observations of a rich stellar field, line_4: one taken at the nominal focus setting, two taken at increments of 50 steps in line_5: the positive direction of the refocussing mechanism, two more at settings in line_6: the negative direction. During OV these increments will probably have to be line_7: larger. Because of backlash it will be necessary to step the line_8: refocus mechanism in the same direction every time. At the completion of a line_9: focussing cycle the mechanism will be returned to its nominal position. line_11: Two filters will be used at the beginning of each FOC observation. line_15: When the first sequence of five exposures is taken at the beginning of an line_16: FOC observation the images should be taken one after another. ! question: 3 section: 2 line_1: line_4: It is assumed that the optimum focus position for the other filters can be line_5: derived from the comparison of the observations in the two reference filters line_6: with measurements taken during FOC ground testing. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO title: DR. category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 301-338-4823 telex: 684-9101-STSCI ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC104 descr_1: 47-TUC-FLD pos_1: RA=0H 24M 06.02S +/- 0.01S, pos_2: DEC=-72D 04' 52.7" +/- 1", equinox: 2000 fluxnum_1: 1 fluxval_1: B=22 +/- 3 ! ! end of fixed targets !
