In each instance the observations will line_3: benefit variously from the spatial resolution and ultraviolet sensitivity line_4: afforded by the Space Telescope and may reveal important facts concerning the line_5: nature of the objects observed. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: NGC 4486. PC exposures with nine medium bandpass filters covering the spectral line_2: range from 2000A to 1 micron. A variety of exposure durations, totaling ~4.5 line_3: hrs. are used to allow for differences in spectrophotometric response. There line_4: are also exposures with the three polarizers (~45 min. total). line_6: All other objects, except as noted, get ~45 min. WFC exposures through each line_7: filter of certain standard filter sets: line_8: 1-color (F606W) : NGC 4753, NGC 6251 line_9: (F555W) : I-Zw-1 (PC), I-Zw-121 (PC) line_11: 2-color (F555W, F785LP) : UGC 6456, Arp 230 line_12: (F555W, F850LP) : NGC 3034, NGC 5128 line_14: 3-color (F555W, F702W, F785LP) : NGC 4476, NGC 4826, IC 4553/4, line_15: NGC 7742, Arp 148, NGC 1275 (90 min. exp.) line_16: 3C405 (90 min. exp.) line_18: 4-color (F230W, F555W, F785LP): NGC 6745 (90 min. exp.) IC 391 ! question: 5 section: 1 line_1: All principal exposures are accompanied by complementary exposures 1 and/or 2 line_2: orders of magnitude shorter in duration, in satisfaction of the dual line_3: requirement to cover a large expected luminous dynamic range and to afford a line_4: means of cosmic-ray discrimination. NOTE: The Institute is NOT to do any line_5: "automatic" cosmic-ray splitting, and CR-SPLIT has NOT been requested ( line_6: explicitly specified exposures will do nicely. line_7: In all cases, exposure (shutter-open) times have been sized to fit, either line_8: singly or in combination, single orbit observing opportunities of 2700 seconds line_9: nominal duration, including lost-time allowances of 120 seconds between line_10: exposures of a single-orbit observing opportunity differ significantly from the line_11: nominal 2700 seconds, the longest indicated exposure time in a single-orbit line_12: observation sequence should be increased or decreased by the appropriate line_13: necessary amount. line_15: For each object there will be special positioning requirements (TBD) and line_16: special orientation requirements. ! question: 6 section: 1 line_1: It is desired that all exposures longer than 1000 sec be taken after the line_2: telescope has passed beyond the brightly lit limb of the Earth (see note on line_3: "dark time" on exposure logsheets). It is not requested that the telescope line_4: actually be within the Earth's shadow. Dark time is needed to minimize line_5: scattered light and maximize S/N faint features. The above guideline of 1000 line_6: sec may need modification after real experience in orbit. ! question: 13 section: 1 line_1: Imaging observations of the following peculiar or interacting galaxies : NGC line_2: 4486, NGC 6745, IC 391, NGC 1275, 3C405, NGC 4826, IC 4553/4, Arp 148, NGC line_3: 4476, NGC 7742, UGC 6456, Arp 230, NGC 3034, NGC 5128, NGC 6251, NGC 4753, line_4: 1Zw1, & 1Zw121. Filters: polarizers & 9 filters from 2000A to 1 micron for NGC line_5: 4486, far UV, visual, red, & near infrared for the next 2 objects, visual, red line_6: & near infrared for the next 7, visual & near infrared for the next 4; and line_7: visual for the last 4. ! !end of general form text general_form_address: lname: LYNDS fname: C. mi: R. category: CON inst: NOAO, KITT PEAK NATIONAL OBSERVATORY addr_1: 950 N.
