abstract:

    line_1:        This proposal defines the spectral cal lamp mini-functional test for the first
    line_2:        order gratings. It is an internal test which makes measurements
    line_3:        of the lamp (SC2). It is used to calibrate the carrousel function,
    line_4:        Y deflections, resolving power, sensitivity, and scattered light. It will be
    line_5:        run for basic calibrations. The carrousel and Y deflection function coefficients
    line_6:        are determined and the PDB will be updated. The wavelength calibration
    line_7:        dispersion constants will be updated in the PODPS calibration data base.

  question:        2
    section:       1
    line_1:        GHRS CAL Objectives:
    line_2:        Obtain routine calibration data for:
    line_3:        1. Carrousel calibration function coefficients.
    line_4:        2. Wavelength calibration dispersion constants.
    line_5:        3. Y deflection function coefficients.
    line_6:        4. Spectral resolving power, instrument profile.
    line_7:        5. Scattered light.
    line_8:        6. Grating to grating relative sensitivity.

!

  question:        3
    section:       1
    line_1:        Observations will be made for the following first order gratings:
    line_4:        Grating G2 (G160M), at 6 carrousel positions, for central wavelengths
    line_5:        1240, 1400, 1520, 1640, 1780, and 1940 Angstroms.
    line_6:        Grating G3 (G200M), at 6 carrousel positions, for central wavelengths
    line_7:        1780, 1940, 2100, 2240, 2380, and 2500 Angstroms.
    line_8:        Grating G4 (G270M), at 6 carrousel positions, for central wavelengths
    line_9:        2375, 2500, 2700, 2900, 3050, and 3200 Angstroms.
    line_12:       At each position, one spectral lamp (sc2) will be observed . Each observation
    line_13:       will use substep pattern 3, with 4 samples per diode. The 2 point comb
    line_14:       addition feature will be used, and a new spectrum Y balance offset will be
    line_15:       calculated for each observation.

!

  question:        5
    section:       1
    line_1:
    line_2:        Repeats approximately every 4 months.
    line_3:        Different gratings are independent tests, and need not
    line_4:        be run together, or in any particular order.
    line_12:       Guiding Tolerance: None - internal test only

!

  question:        7
    section:       1
    line_1:        1. Coefficients for the carrousel function and Y deflection function are
    line_2:        determined and entered into the project database. These coefficients will
    line_3:        be used to construct OSTs for subsequent observations using this grating.
    line_4:        2. Wavelength calibration dispersion constants are entered into the PODPS
    line_5:        calibration database.
    line_6:        3. Other parameters are derived for performance monitoring.

!

  question:        8
    section:       1
    line_1:        This is an internal test and does not require any special pointing of the
    line_6:        telescope. This test does not require the GHRS to be the prime science
    line_7:        instrument. There is no target list with this proposal.

!

  question:        10
    section:       1
    line_1:        1. Test design support.
    line_3:        2. Test execution support team.
    line_5:        3. Data analysis facilities.
    line_7:        4. Data analysis personnel.
