MANAGER ! end of coverpage abstract: line_1: The objective of this activity is twofold: firstly, to establish the position line_2: of the coronographic fingers in SDS coordinates, and, secondly, to establish line_3: the best internal focus of the f/96 chain and verify its resolution line_4: performance. Both an extended object with structure and a series of point line_5: sources should be imaged to obtain the point spread function and the knife line_6: edge function. The procedure is to be repeated for the f/288. The f/96 and line_7: the f/288 best focus positions determined by these observations will be used to line_8: update the flight software, and the necessary for performing future FOC line_9: observations. line_11: Finally a series of esposures will be taken in each mode with all the focus line_12: information updated. line_14: Revised 10/11/89 & 10/26 by L. Nagel to accomadate redline revisions & match line_15: Implementation Plans. line_17: Revised 12/5/89 to accommodate results of meetings line_18: with proposer. ! ! end of abstract general_form_proposers: lname: LAURANCE fname: R. mi: J. inst: ESA/FOC country: HOLLAND esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: i) Extended object - central bar of Orion Nebula. line_2: The focussing procedure is based on 5 observations, one taken at the nominal line_3: focus setting, two taken at increments of 30 steps in the positive direction line_4: of the refocussing mechanism, two more at settings in the negative direction. line_5: The focussing procedure on the ground is then based on the analysis of the edge line_6: function associated with the image of the extended source behind the line_7: coronographic fingers. line_9: ii) Point source - The procedure is based on 5 observations of a rich stellar line_10: field, 47 Tuc, one taken at the nominal focus setting, two taken at increments line_11: of 30 steps in the positive direction of the refocussing mechanism, two more line_12: at settings in the negative direction. The procedure should be repeated with line_13: one or two filters in order to confirm the earlier ground measurements of line_14: optical path difference. The resulting best focus position requires uplinking line_15: into the NSSC-1 memory. line_17: The procedure is to be repeated for the f/288, both for the extended object and line_18: the point source. line_20: iii) Point Source - The f/96 detector internal (electrical) focus line_21: will be verified using a rich stellar field (47 Tuc). ! question: 4 section: 1 line_1: The observations are required to establish the position of the coronographic line_2: fingers in SDS coordinates, and to establish the best focus positions of the line_3: f/96 and f/288 chains. ! question: 5 section: 0 line_1: The two targets should be observed within a week of each other unless prevented line_2: by seasonal constraints. line_4: Note to scheduler: line_6: Exposure lines 6 through 9 should be executed first (in order). A gap of 2 days line_7: is required for data analysis, and uplink of new values. Lines 10-14 should line_8: then be executed followed by a further 2 day gap. The remaining lines should line_9: then be executed. line_11: FOC should be transitioned to STANDBY MODE B/2 during SAA passages. line_13: PREREQUISITES: line_14: FOC011(prop 1488) and FOC012 (prop 1497) (establishing the position line_15: of the f/96 image) must have been successfully completed line_16: prior to initiating this proposal. ! question: 7 section: 1 line_1: Both an extended object with structure and a series of point sources will be line_2: imaged to obtain the point spread function and the line spread function. line_4: The focussing procedure using an extended object is based on 5 observations, line_5: one taken at the nominal focus setting, two taken at increments of 30 steps in line_6: the positive direction of the refocussing mechanism, two more at settings in line_7: the negative direction. line_9: The focussing procedure on the ground is then based on the analysis of the edge line_10: function associated with the image of the extended source behind the line_11: coronographic fingers. line_13: The procedure using a POINT source is based on 5 observations of rich stellar line_14: fields, one taken at the nominal focus setting, as established above, two taken line_15: at increments of 30 steps in the positive direction of the refocussing line_16: mechanism, two more at increments of 30 steps in the negative direction. line_18: The images will be displayed (not necessarily in real-time) and cross cuts will line_19: be made over suitable stars; the best focus is achieved when the star image is line_20: of minimum size. line_22: The procedure will be repeated with one or two filters in order to confirm the line_23: earlier ground measurements of optical path difference. ! !end of general form text general_form_address: lname: LAURANCE fname: R. category: PI inst: ESA/ESTEC addr_1: POSTBUS 299 city: NOORDWIJK country: NETHERLANDS phone: NL-2200 AG telex: 39098 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC1976 descr_1: CENTRAL BAR OF ORION NEBULA pos_1: RA=5H 32M 52S +/- 1S, pos_2: DEC=-5D 23' 30" +/- 0.5" equinox: 1950 ! targnum: 2 name_1: NGC104 descr_1: 47 TUC pos_1: RA=0H 20M 20.70S +/- 0.1S, pos_2: DEC=-72D 04' 56.05"+/- 1.0" equinox: 2000 ! targnum: 3 name_1: NGC188/J descr_1: ^ pos_1: RA=0H 46M 40.761S +/- 0.01S, pos_2: DEC=+85D 14' 40.52" +/- 1", pos_3: PLATE-ID=ZZZZ equinox: 2000 ! ! end of fixed targets !
