PLANETARY SCI. ! end of coverpage abstract: line_1: We propose to observe 10 galaxy nuclei from the original GTO line_2: proposal 1118 that otherwise will be lost for lack of time. line_3: These 10 include seven of the nearest normal spiral galaxies, from line_4: types S0 through Sc. This is the largest sample of late-type line_5: spiral nuclei being done with HST that we know of and is essential line_6: to the collection of a representative catalog of all galaxy line_7: types. The remaining three galaxies include a classic Seyfert line_8: galaxy (NGC 4151), a protype emission- line elliptical (NGC 1052), line_9: and a well known blue elliptical that is a post-starburst and line_10: merger candidate (NGC 1600). ! ! 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: F555W PC6 images of the nuclear regions of 10 spiral and abnormal line_2: galaxies are requested. Objects to be centered in PC6 location, as line_3: used in the STScI PSF monitor program. PSF Monitor exposures should line_4: provide adequate information for deconvolution purposes; no additional line_5: PSF stars are needed. Exposures should give 1300DN in the nuclear line_6: pixel, though ground-based estimates of the surface brightness of line_7: several galaxies are uncertain. Experience with existing HST galaxy line_8: images suggest that the likelihood of saturation is small, however. line_9: Exposures are duplicated to provide CR-splits. PCS mode is to be line_10: Coarse Track, as the PC is undersampled. Jitter data are required line_11: to reconstruct the true PSF. ! question: 4 section: 1 line_1: These nuclei are uniformly unresolved from the ground and require line_2: HST's narrower PSF. Existing HST images of galaxy nuclei are revealing line_3: a wealth of different structures and behavior that cannot be discerned line_4: from ground-based images. ! question: 7 section: 1 line_1: The WFPC IDT has considerable experience with reducing and analyzing line_2: galaxy nuclear images. Proven software exists for flattening and line_3: removing the instrumental signature, deconvolution, isophote fitting, line_4: and multiple-component fitting, to name but a few functions. These line_5: data will be handled in parallel with the other data expected from line_6: GTO 1118. ! question: 8 section: 1 line_1: Accurate PSFs are essential. We are relying on the weekly STScI line_2: PSF monitoring program in F555W/PC6, and we want our galaxies to be line_3: centered at the same chip position used for the monitor. See remarks line_4: in Section 3. line_5: We will also require accurate flat fields in F555W/PC6 to +/- 1% in line_6: the central 200x200 pixels and +/- 2% over the whole chip. Jitter line_7: data are required to reconstruct the true PSFs. ! !end of general form text general_form_address: lname: LAUER fname: TOD mi: R. category: CON inst: NOAO/KPNO addr_1: 950 N.
