abstract:

    line_1:        We propose to use the FGS in TRANSFER mode to examine, at
    line_2:        high angular resolution, two known binary pairs in an effort
    line_3:        to establish the orbital elements of these pairs near their
    line_4:        periastron, which is not possible from the ground. Knowledge
    line_5:        of the orbital parameters will lead to a precise
    line_6:        determination of the stellar mass of each component. It is
    line_7:        expected that the separations of the component stars in each
    line_8:        pair is currently about 0.050 seconds of arc with about one
    line_9:        magnitude difference in brightness, thus precise measurements
    line_10:       with the Hubble Space Telescope can be readily obtained at
    line_11:       this time.

  question:        3
    section:       1
    line_1:        Line 1, page 11 defines, for each target, an  observation consisting
    line_2:        of a set of continuous scans at a scan rate of 0.012 arcsec per
    line_3:        sec and a scanlength of 1.2 arcsec per interferometer axis. There are
    line_4:        5 scans/observation (total exposure time 500 seconds), sufficient to
    line_5:        permit precise determination of the separations and magnitude dif-
    line_6:        ferences. Exposures are requested as follows:
    line_7:        Observation (line 1, page 11) of each target during cycle 0.

  question:        7
    section:       1
    line_1:        Data reduction and analysis will be carried out with the use of
    line_2:        of algorithms and software developed and being developed by ST
    line_3:        Astrometry Team members.  While initial data reduction is expected to
    line_4:        be carried out at STScI, subsequent detailed analyses will be under-
    line_5:        taken at the investigator's home institutions.

  question:        10
    section:       1
    line_1:        Computer facilities and software will be provided for
    line_2:        detailed data analyses.
