abstract:

    line_1:        We propose to acquire a deep 1 micron image of the Galactic center using
    line_2:        the PC configuration of the HST. With such an image, it will be possible
    line_3:        to resolve structure on a scale of about 1000 AU at the Galactic center,
    line_4:        thereby providing valuable morphological information about the complex
    line_5:        IRS 16 region. The acquired data will also provide intrinsic color
    line_6:        information about stars in the Galactic center and establish an
    line_7:        astrometric base that can be used in the future to measure the proper
    line_8:        motions of the stars in and around IRS 16.

  question:        3
    section:       1
    line_1:        A SERIES OF EXPOSURES WILL BE ACQUIRED WITH THE PC
    line_2:        CONFIGURATION AND THE F1024M FILTER WHICH SHUOLD RESOLVE THE
    line_3:        VARIOUS COMPONENTS OF IRS 16 WITH SIZES GREATER THAN 0.1".
    line_4:        ALSO, FOUR 200S EXPOSURES USING THE PC CONFIGURATION AND
    line_5:        F785LP FILTER WILL BE ACQUIRED TO IDENTIFY FIELD STARS THAT MAY
    line_6:        CREATE CONFUSION IN RESOLVING THE COMPONENTS OF IRS 16. PREVIOUS
    line_7:        WORK BY HENRY ET AL. (AP. J. LETTERS, 285, L27, 1984) HAS ALREADY
    line_8:        REVEALED A STAR WITH A 0.98 MICRON MAGNITUDE OF ABOUT 18,
    line_9:        ROUGHLY 1" FROM IRS 16C AND THE PROPOSED COADDED 200S EXPOSURES WILL
    line_10:       BE USEFUL IN OUR EFFORTS TO IDENTIFY FLUX FROM THIS STAR IN THE
    line_11:       LONGER WAVELENGTH EXPOSURES.
