Abstract The FOS will be used with small apertures to map the stellar velocity dispersion and rotation in a grid covering the central 1" of NGC224 (M31). The velocity disperions and rotation curves will be used to model the nuclear dynamics and to measure the nuclear M/L. Line strengths will be used to measure changes in the stellar populations in the central 1". FOS spectra of emission-line clouds within the nuclear region will be used to establish their physical characteristics, ionization mechanisms, and dynamics. ------------------------------------------------------------------------------------ 8.

Ford SPACE TELESCOPE SCIENCE USA INSTITUTE ------------------------------------------------------------------------------------ 3. Description of proposed observations. FOS observations of NGC 224 (M31) will consist of spectra at locations along the major axis (position angle 45 deg) of 0.0", +/-0.25", +-0.50", and +/-0.75" using grating G570H and the 0.3" aperture. Two additional points at +/-1.0" will be obtained using the 0.5" aperture. All these major axis positions have been moved from the FOS/GTO baseline program into this augmented time proposal to unify the target acquisition and ensure that all positions in the nuclear region are registered at precisely known positions. Along the minor axis (Position angle 135 deg) we will obtain spectra at +/-0.25", +-0.50", and +/-0.75" using grating G570H and the 0.3" aperture. Additional spectra at 8 off-axis points parallel to and on either side of the major axis ((+/-0.25", +/-0.25") and (+/-0.25", +/- 0.5")) using the same grating/aperture combination will also be obtained. Acquisition will be done using a binary search on a nearby star identified in a WFC image, followed by two small peak-ups on the brightest peak in the nucleus of NGC 224. For use as a template star in Fourier quotient deconvolutions, we will obtain a spectrum of the K star F193 using the same grating and aperture. Internal wavelength calibrations will be obtained through the same grating and aperture on each of the M31 exposures and on F193. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The observations of the nuclear region of NGC 224 (M31) are arranged on a finely spaced (0.25") rectangular grid along the major and minor axes. To ensure the precise relative registration of the pointing positions in the grid, we wish to perform only one target acquisition and use only small angle maneuvers to obtain the spectra at each of the 23 ensuing points in the grid. The requisite observations have been indicated with GROUP NO GAP in the exposure log sheet. The observations of the star F193 are for use as a template in the Fourier quotient analysis of the NGC 224 nuclear spectra. To avoid any potential temporal changes in the instrument that might invalidate the use of these observations as a template, we request that they be scheduled within 60 days of the NGC 224 observations. Page 3 ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. Precise wavelength calibrations are required to study the kinematics of the gas and stars in the nucleus of NGC 224 (M31). Internal WAVE calibrations are required for observations using grating G570H as indicated in the exposure log. These calibration exposures must be obtained immediately following the science exposures with no intervening motion of the FOS filter/grating wheel or apertures. ------------------------------------------------------------------------------------ 8.
