It is assumed line_10: that the observations will occur when the target is line_11: opposite the Sun and the strip is oriented so that at the line_12: nominal roll for this date, the WFPC2 fields overlap in a line_13: chevron pattern. line_15: These exposures will also be useful for star count line_16: studies bearing on galactic structure. line_18: This program is the combined GTO time of Groth and line_19: Schroeder and is coordinated with a WFPC1 GTO program. ! ! end of abstract general_form_proposers: lname: GROTH fname: EDWARD title: PROF. mi: J. inst: PRINCETON UNIVERSITY country: USA ! lname: SCHROEDER fname: DANIEL title: PROF. mi: J. inst: BELOIT COLLEGE country: USA ! lname: KRISTIAN fname: JEROME title: DR. inst: MT. WILSON AND LAS CAMPANAS OBSERVATORIES. country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The observations are a strip of WFPC2 fields. The target line_2: fields are at ecliptic longitude 180 degrees so the optimum line_3: date to observe is March 21. The orientation of the strip line_4: has the same position angle as the nominal roll on this line_5: date. Adjacent fields are displaced by 91.9239 arcseconds in line_6: the V3 direction. This causes the fields to overlap in a line_7: chevron pattern with 10 arcseconds of overlap along the line_8: edges of the WFC chips. The exposures are 4400 seconds long, line_9: in I and 2800 seconds long in V but are divided into line_10: four non-cr-split exposures of 1100 and 700 seconds. line_11: The CR problem is expected to be more severe for line_12: WFPC2 than WFPC1, and it is believed that CR splitting a line_13: single 4400 second exposure into two 2200 second exposures line_14: will not provide good enough faint CR rejection. It is line_15: intended that one I and one V exposure be done each orbit line_16: so that a there are a total of 4 orbits per field. ! question: 4 section: 1 line_1: An "average" galaxy (as opposed to a dominant cluster line_2: galaxy) has a core radius of only several hundred parsecs line_3: and falls off rapidly beyond the core. A core radius this line_4: small is unresolved (even by the HST) for distant galaxies. line_5: As long as the core radius is on the order of or smaller line_6: than a resolution element, the signal to noise is line_7: contributed almost entirely by the central pixel (even line_8: though most of the light is at larger radii). This is line_9: because the total light goes up with logarithm of the line_10: radius, but the total background light goes up with the line_11: square of the radius. Thus the ST will be unsurpassed for line_12: detecting "average galaxies" which are just the kind of line_13: galaxies required to perform statistical and correlation line_14: studies. ! question: 5 section: 1 line_1: There are no real time requirements. ! question: 6 section: 1 line_1: Specific rolls has been requested in order to optimize line_2: the overlap of the WFPC2 fields along the strip (with random line_3: rolls, there could be cases with no overlap). The rolls line_4: given in the ORIENT special requirement are the position line_5: angle of the U3 axis with respect to the equinox 2000.0 line_6: north pole. line_8: Dark time has been requested in order to provide the line_9: maximum signal to noise for faint objects with a given line_10: exposure time. A day of observation has been chosen so that line_11: the observations will occur at very low Zodiacal light line_12: brightnesses when dark time is maximized. line_14: Un-interrupted exposures are necessary in order to line_15: minimize the WFC readout noise. ! ! question: 8 section: 1 line_1: This program is the combined GTO program of Groth line_2: and Schroeder and is coordinated with one of the line_3: GTO programs of the WFPC1 IDT. ! question: 9 section: 1 line_1: Lots ! question: 10 section: 1 line_1: Computing facilities, graduate students, post-docs, line_2: publication resources. ! !end of general form text general_form_address: lname: GROTH III fname: EDWARD mi: J. title: PROF. category: PI inst: PRINCETON UNIVERSITY addr_1: PHYSICS DEPARTMENT addr_2: JADWIN HALL city: PRINCETON state: NJ zip: 08544 country: USA phone: (609) 258-4361 ! lname: SCHROEDER fname: DANIEL mi: J. title: PROF. category: CON inst: DELOIT COLLEGE addr_1: DEPARTMENT OF PHYSICS addr_2: BELOIT COLLEGE city: BELOIT state: WI zip: 53511 country: USA phone: (608) 363-2258 ! lname: KRISTIAN fname: JEROME title: DR. category: CON inst: MT.
