ST observations are required in order to reach line_5: the faint limiting magnitudes that are necessary to provide sufficient spatial line_6: resolution to permit accurate photometry. ! ! end of abstract general_form_proposers: lname: BAHCALL fname: JOHN title: DR. mi: N. inst: INSTITUTE FOR ADVANCED STUDY country: USA ! lname: FREEMAN fname: KENNETH inst: MT.

THE PRIMARY TARGETS ARE: 1,3,5,7,9. THE PARALLEL TARGETS line_3: ARE: 2,4,6,8,10. line_4: FOR EACH PRIMARY TARGET, TWO IMAGES WILL BE ACQUIRED USING THE WF CAMERA, line_5: ONE WITH F555W AND ONE WITH F785LP.

IF A line_12: PRIMARY OBSERVATIONS CAN ONLY BE SCHEDULED DURING THE REQUESTED CYCLE BY line_13: IGNORING ITS PARALLEL OBSERVATION, THEN IN THIS CASE IGNORE THE PARALLEL line_14: OBSERVATION. ! question: 4 section: 1 line_1: ST observations are essential in order to : (1) reach the faint limiting line_2: magnitudes beyond the peak of the luminosity function; (2) to separate line_3: globular clusters from galaxies on the basis of their image morphology; and (3) line_4: to have sufficient resolution to measure tidal radii. We need to observe line_5: globular clusters to at least apparent visual magnitude of 25.7 mag in order to line_6: be well beyond the expected peak of the globular cluster luminosity function. ! question: 5 section: 1 line_1: The parallel observations are desirable, but not essential. If a primary line_2: observation can only be scheduled during the requested cycle by ignoring its line_3: parallel observation, then in this case ignore the parallel observation. ! question: 6 section: 1 line_1: Dark time is required to reach the desired faint limiting magnitudes. ! question: 7 section: 1 line_1: Data reduction and analysis will be performed on the DEC equipment line_2: available at the Institute for Advanced Study. ! question: 8 section: 1 line_1: Deep ground based observations will be obtained prior to launch. ! question: 10 section: 1 line_1: Computing and research assistance will be provided as necessary. ! question: 13 section: 1 line_1: These observations will determine the luminosity functions and tidal radii of line_2: globular clusters around 3 galaxies (NGC 4472, NGC 4374, NGC 4526) in the Virgo line_3: cluster of galaxies and 3 galaxies (NGC 1380, NGC 1399, and NGC 1404) in the line_4: Fornax cluster of galaxies. ! !end of general form text general_form_address: lname: BAHCALL fname: JOHN mi: N. title: DR. category: PI inst: INSTITUTE FOR ADVANCED STUDY addr_1: OLDEN LANE city: PRINCETON state: NJ zip: 08540 country: USA phone: (609) 734-8054 telex: 837 680 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC4472F1 descr_1: FIELD NEAR descr_2: NGC4472 pos_1: RA=12H 27M 22.97S+/-0.1S, pos_2: DEC=+08D 18' 54.8"+/-2" equinox: 1950 pm_or_par: NO ! targnum: 2 name_1: NGC4472F2 descr_1: FIELD NEAR descr_2: NGC4472 pos_1: RA=12H 27M 04.47S +/- 0.1S, pos_2: DEC=+08D 14' 12.2" +/- 2" equinox: 1950 pm_or_par: NO ! targnum: 3 name_1: NGC4526F1 descr_1: FIELD NEAR descr_2: NGC4536 pos_1: RA=12H 31M 28.82S+/-0.1S, pos_2: DEC=+08D 01' 16.5"+/-2" equinox: 1950 pm_or_par: NO ! targnum: 4 name_1: NGC4526F2 descr_1: FIELD NEAR descr_2: NGC 4526 pos_1: RA=12H 31M 36.01S +/- 0.1S, pos_2: DEC=+07D 54' 57.2" +/- 2" equinox: 1950 pm_or_par: NO ! targnum: 5 name_1: NGC4374F1 descr_1: FIELD NEAR descr_2: NGC 4374 pos_1: RA=12H 22M 32.76S +/- 0.1S, pos_2: DEC=+13D 12' 51.3" +/- 2" equinox: 1950 pm_or_par: NO ! targnum: 6 name_1: NGC4374F2 descr_1: FIELD NEAR descr_2: NGC 4374 pos_1: RA=12H 22M 30.92S +/- 0.1S, pos_2: DEC=+13D 06' 18.2" +/- 2" equinox: 1950 pm_or_par: NO ! targnum: 7 name_1: NGC1380F1 descr_1: FIELD NEAR descr_2: NGC 1380 pos_1: RA=03H 34M 18.25S+/-0.1S, pos_2: DEC=-35D 06' 21.0"+/-2" equinox: 1950 pm_or_par: NO ! targnum: 8 name_1: NGC1380F2 descr_1: FIELD NEAR descr_2: NGC 1380 pos_1: RA=03H 34M 50.17S +/- 0.1S, pos_2: DEC=-35D 07' 04.3" +/- 2" equinox: 1950 pm_or_par: NO ! targnum: 9 name_1: NGC1404F1 descr_1: FIELD NEAR descr_2: NGC 1404 pos_1: RA=03H 36M 52.21S+/-0.1S, pos_2: DEC=-35D 44' 00.8"+/-2" equinox: 1950 pm_or_par: NO ! targnum: 10 name_1: NGC1399F1 descr_1: FIELD NEAR descr_2: NGC 1399 pos_1: RA=03H 36M 36.56S+/-0.1S, pos_2: DEC=-35D 38' 16.6" +/-2" equinox: 1950 pm_or_par: NO ! targnum: 11 name_1: SN1987A descr_1: SUPERNOVA REMNANT pos_1: RA=05H 35M 49.9S+/-0.1S, pos_2: DEC=-69D 17' 58" +/-1.0" equinox: 1950 pm_or_par: NO fluxnum_1: 1 fluxval_1: V=13.0 +/- 1.0 ! ! end of fixed targets !
