Line strengths will be used to measure changes in the line_7: stellar populations in the central 1". FOS spectra of any line_8: emission-line clouds within the nuclear region will be used to line_9: establish their physical characteristics, ionization line_10: mechanisms, and dynamics. ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: BURBIDGE fname: E.

We will use the 0.3" aperture on the nucleus and at line_3: positions of +/-0.25" along the major and minor axes. Additional line_4: spectra through the 0.5" aperture using the same grating will be line_5: obtained at positions of +/-0.50" along the major and minor axes. line_6: Acquisition will be done using a binary search on a nearby star line_7: identified in a WFC image, followed by two small peak-ups on the line_8: the nucleus of NGC 4472. We will use spectra of the K star F193 line_9: obtained with the same grating and aperture during Cycle 2 line_10: observations as a template star in Fourier quotient deconvolutions. line_11: Internal wavelength calibrations will be obtained through the same line_12: grating and aperture on each of the NGC 4472 exposures. ! question: 4 section: 1 line_1: NGC 4472 has been observed extensively from the ground line_2: both photometrically and spectroscopically. Our dispersion line_3: measurements at 0.5" will be used to tie in to ground-based line_4: measurements at larger radii. ! question: 5 section: 1 line_1: The observations of the nuclear region of NGC 4472 are arranged line_2: on a finely spaced (0.25") rectangular grid along the major and minor line_3: axes. To ensure the precise relative registration of the pointing line_4: positions in the grid, we wish to perform only one target acquisition line_5: and use only small angle maneuvers to obtain the spectra at each of line_6: the 9 ensuing points in the grid. The requisite observations have line_7: been indicated with GROUP NO GAP in the exposure log sheet. ! question: 6 section: 1 line_1: Precise wavelength calibrations are required to study the kinematics of line_2: the gas and stars in the nucleus of NGC 4472. Internal WAVE line_3: calibrations are required for observations using grating G570H as line_4: indicated in the exposure log. These calibration exposures must be line_5: obtained immediately following the science exposures with no line_6: intervening motion of the FOS filter/grating wheel or apertures. ! question: 7 section: 1 line_1: The FOS spectra will be processed using the latest available line_2: calibration data to transform the raw count data into flux-calibrated, line_3: wavelength-calibrated images. Velocities and dispersions for the line_4: NGC 4472 spectra will be obtained using Fourier quotient routines line_5: operating in IRAF based on the algorithms outlined by line_6: Sargent et al (1977). In addition, we will test more complex line_7: dynamical models for NGC 4472 by folding spectra of our template star line_8: through the dynamical model and the point response of HST and line_9: integrating the resulting spectra over the FOS apertures line_10: (eg, Dressler & Richstone 1988; Kormendy 1988). This will allow us to line_11: test the validity of our conclusions in the face of complications due line_12: to the aberrated images produced by the primary mirror. ! question: 8 section: 1 line_1: PC and WFC images of NGC 4472 (when available) will be measured for line_2: precise target coordinates, so that the FOS observations can be done line_3: as blind offsets from a nearby isolated star. line_5: While not officially listed as co-investigators, the following line_6: scientists are actively involved in research with the FOS GTO team and line_7: are expected to contribute significantly to its scientific output: line_8: W. P. Blair, S. Caganoff, G. A. Kriss, A. Uomoto (JHU); line_9: R. Antonucci (UCSB); L. Armus (Cal Tech); I. Evans, A. Kinney (STScI); line_10: L. Dressel (ARC); R. Allen, P. Smith (U. Arizona); line_11: S. Anderson (U. Washington); R. Cohen, R. Hier, V. Junkarrinen, line_12: E. Rosenblatt (UCSD). ! question: 9 section: 1 line_1: Since there are 29 separate FOS IDT GTO programs, only those related line_2: to the current proposal are listed here. line_4: 1040 - Velocity Dispersions in the Nuclei of Giant Ellipticals line_5: 1041, 3191, 3276 - The Nucleus of Normal and Starburst Galaxies line_6: 1044, 3193, 3277 - Stellar and Gas Dynamics in Normal Galaxies ! question: 10 section: 1 line_1: All resources for these programs are provided by NASA through the line_2: FOS IDT contract NAS 5-29293. ! !end of general form text general_form_address: lname: FORD fname: HOLLAND mi: C. category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC4472 descr_1: E,303,910 pos_1: TBD-EARLY, pos_2: RA=12H 29M 46.8S +/- 1", pos_3: DEC=+08D 00' 02" +/- 1" equinox: 2000 rv_or_z: V=800 fluxnum_1: 1 fluxval_1: F(5556)=8.5E-17 ! targnum: 2 name_1: NGC4472-SE1 descr_1: E,303,913 pos_1: R=0.25" +/- 0.02", pos_2: PA=170D +/- 15D, pos_3: FROM 1 comment_1: F(5556)=8.5E-17 fluxnum_1: 1 ! targnum: 3 name_1: NGC4472-SE2 descr_1: E,303,913 pos_1: R=0.50" +/- 0.02", pos_2: PA=170D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=2.4E-16 fluxnum_1: 1 ! targnum: 4 name_1: NGC4472-NW1 descr_1: E,303,913 pos_1: R=0.25" +/- 0.02", pos_2: PA=350D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=8.5E-17 fluxnum_1: 1 ! targnum: 5 name_1: NGC4472-NW2 descr_1: E,303,913 pos_1: R=0.50" +/- 0.02", pos_2: PA=350D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=2.4E-16 fluxnum_1: 1 ! targnum: 6 name_1: NGC4472-NE1 descr_1: E,303,913 pos_1: R=0.25" +/- 0.02", pos_2: PA=80D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=8.5E-17 fluxnum_1: 1 ! targnum: 7 name_1: NGC4472-NE2 descr_1: E,303,913 pos_1: R=0.50" +/- 0.02", pos_2: PA=80D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=2.4E-16 fluxnum_1: 1 ! targnum: 8 name_1: NGC4472-SW1 descr_1: E,303,913 pos_1: R=0.25" +/- 0.02", pos_2: PA=260D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=8.5E-17 fluxnum_1: 1 ! targnum: 9 name_1: NGC4472-SW2 descr_1: E,303,913 pos_1: R=0.50" +/- 0.02", pos_2: PA=260D +/- 15D, pos_4: FROM 1 comment_1: F(5556)=2.4E-16 fluxnum_1: 1 ! targnum: 10 name_1: NGC4472-OFFSET descr_1: A,140 pos_1: TBD-EARLY, pos_2: RA-OFF=0.0S +/- 20S, pos_3: DEC-OFF=0.0" +/- 300", pos_4: FROM 1 fluxnum_1: 1 fluxval_1: V=15.6 fluxnum_2: 2 fluxval_2: B-V=1.0 ! ! end of fixed targets !
