At the completion of a focussing cycle the line_7: mechanism will be returned to its nominal position. line_9: Two filters will be used for the F/48 and the F/95. ! 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 reference filters line_6: with measurements taken during FOC ground testing. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC6752 descr_1: GLOBULAR CLUSTER FIELD pos_1: RA=19H 06M 27.3S +/- 0.01S, pos_2: DEC=-60D 03' 50.5" +/- 1", equinox: 1950 fluxnum_1: 1 fluxval_1: B=21 +/- 2 ! ! end of fixed targets !
