    line_1:        The goal of this test is to determine whether astrometric data can be obtained
    line_2:        on stars surrounded by nebulosity.

  question:        2
    section:       1
    line_1:        Astrometric observations of objects embedded in nebulosity and near bright
    line_2:        stars are of great interest. A significant fraction of the GTO observations
    line_3:        will be made of such objects. The ability of the FGSs to make such
    line_4:        observations must be verified.

!

  question:        3
    section:       1
    line_1:        1) Acquire guide stars and position HST so the target stars
    line_2:        fall in FGS 3 FOV. Star Neb1-2 should be at X=Y=O.
    line_4:        2) Scan three "nebular stars" with F583W filter with
    line_5:        FGS 3 as astrometer.
    line_6:        3) Repeat step 2 with the F550W and F605W filters.
    line_7:        4) Wait 30D to validate POS mode K-factors then
    line_8:        measure three "nebular stars" with F583W filter for
    line_9:        FGS 3 as astrometer.
    line_10:       5) Measure the three stars with the F550W and F605W filters.

  question:        5
    section:       0
    line_1:
    line_4:        The Orion (field 1) and Trifid (field 2) nebulae
    line_5:        are available at 1/2 year intervals:
    line_6:        Orion from June 22 - December 21,
    line_7:        Trifid from December 22 to June 21.
    line_12:       Use Orion if possible.

!

  question:        7
    section:       1
    line_1:        The combined FGS data will be analyzed for continuity, outliers, statistical
    line_2:        distribution, and positional stability. In addition, consistancy will be
    line_3:        checked against the relative magnitudes and positions from ground based
    line_4:        measurements. The ADRS system within SDAS will be used to analyze the data.
    line_5:        No values to be included in the calibration data base will be generated by
    line_6:        this test.

!

  question:        8
    section:       1
    line_1:        All FGS numbrs refer to BAY numbers.

!

  question:        10
    section:       1
    line_1:        ADRS will be available in Austin to support further analysis of the data.
