In M31 our target is one line_4: giant HII region (NGC206) and its neighborhood. In M33 our line_5: targets is a giant HII region (NGC604) and its surrounding line_6: neighborhood. Deep U, V, I frames (F336W,F555W,F814W) will line_7: be used to construct color-magnitude and color-color line_8: diagrams, and to derive age, metallicity, reddening, and line_9: luminosity functions. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES title: PROF. mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Stepped exposures with the WFC will be taken using three line_2: filters (F336W, F555W, F814W) in a field in M31 and in M33. line_3: An additional narrow-band image (F656N) will be taken of the line_4: M33 HII region. The exposures are designed to record the line_5: brighter stars (not foreground) without saturation and yet line_6: give a reasonable limiting magnitude for color-magnitude line_7: diagram analysis. ! question: 6 section: 1 line_1: Exposures that are uninterrupted (except for CR-splits) are line_2: needed to maximize the S/N. For all exposures >=500 sec, we line_3: request dark time. That is needed to minimize scattered line_4: light. By dark time we mean that the telescope should be line_5: beyond the brightly lit limb of the Earth, in the dark half line_6: of the orbit. We do not require that the telescope actually line_7: be within the Earth's shadow. ! question: 13 section: 1 line_1: WFPC2 exposures will be obtained in the PC and WFC chips for line_2: three broad passbands (U, V, and I) in giant HII regions line_3: of M31 and M33, encompassing the surrounding arm and disk line_4: regions. Ages, reddenings, metallicities, and luminosity line_5: functions will be derived. ! !end of general form text general_form_address: lname: WESTPHAL fname: JAMES mi: A. title: PROF. category: PI inst: CALTECH addr_1: MAIL STOP 170-25 addr_2: DIVISION OF GEOLOGICAL addr_3: & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: 818-395-4900 ! lname: BAUM fname: WILLIAM mi: A. title: PROF. category: CON inst: UNIVERSITY OF WASHINGTON addr_1: ASTRONOMY DEPARTMENT addr_2: 2124 NE PARK ROAD city: SEATTLE state: WA zip: 98105 country: USA phone: 206-527-4306 ! lname: HUNTER fname: DEIDRE mi: A. category: CON inst: LOWELL OBSERVATORY addr_1: 1400 WEST MARS HILL ROAD city: FLAGSTAFF state: AZ zip: 86001 country: USA phone: 602-774-3358 ! lname: FABER fname: SANDRA mi: M. title: PROF. category: CON inst: UNIVERSITY OF CALIFORNIA addr_1: LICK OBSERVATORY addr_2: NATURAL SCIENCES II, BLDG 160 city: SANTA CRUZ state: CA zip: 95064 country: USA phone: 408-459-2944 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: M31-FIELDN206 descr_1: E, 301, C, 203 pos_1: RA = 0H 37M 45.9S +/-.1S, pos_2: DEC= +40D 27' 31" +/-1" equinox: 1950 comment_1: GIANT HII REGION comment_2: NGC206 IN M31 fluxnum_1: 1 fluxval_1: V = 25.2 +/- 0.5 ! targnum: 2 name_1: M33-FIELDN604 descr_1: E, 301, G, 503 pos_1: RA= 1H 31M 43.7S +/- 0.1S, pos_2: DEC= +30D 31' 40" +/-1" equinox: 1950 comment_1: GIANT HII REGION IN M33 fluxnum_1: 1 fluxval_1: V = 25.2 +/- 0.5 ! ! end of fixed targets !
