abstract:

    line_1:        Zeta Oph is one of the best studied lines of sight for interstellar
    line_2:        absorption lines. Interstellar observations represent one of the primary
    line_3:        scientific objectives of the Goddard High Resolution Spectrograph. The
    line_4:        goal of this program is to observe weak absorption lines of interstellar
    line_5:        molecules with the highest possible spectral resolution, S/N ratio,
    line_6:        photometric precision and wavelength accuracy. These observations will
    line_7:        demonstrate the limits of GHRS performance for measurements of very
    line_8:        weak spectral features.
    line_10:       submitted March 1992 for revised cycle 2 without side 1
    line_11:       use augmentation time if available, baseline time if not
    line_12:       Potential augmentation time is 5.0 hours.

  question:        3
    section:       1
    line_1:        Five weak molecular absorption lines will be observed. They are:
    line_2:        H2O (1240A), N2 (1273A), HCl (1290A), CH2 (1410A), and CS (2576A)
    line_3:        The observing sequence will be:
    line_4:        1. onboard acq into LSA followed by image
    line_5:        2. SSA peakup using "return" followed by image
    line_6:        3.
    line_7:        4. short ACCUM with star moved out of SSA by 1 arc second
    line_8:        5. compute new spybal offset and wavecal with SC2
    line_9:        6.
    line_10:       7. short accum mode exposure with star back in SSA
    line_11:       8. 1 set of FPSPLIT exposures to achieve very high S/N
    line_13:       Lines shortward of 1800 use G160M, longward use Ech-B

!

  question:        5
    section:       1
    line_1:        There are no realtime requirements.
    line_3:        We must have a working SSA peakup routine available.
    line_6:        Note that there is non-standard commanding in several places:
    line_7:        - image mode maps of SSA with no leading defcal - bright star
    line_8:        line 50
    line_9:        - new spybal computed at exact carrousel position and echelle order
    line_10:       lines 105,155,205,255,305,405

!

  question:        7
    section:       1
    line_1:        Most of the reduction and analysis will be done with IDT facilities. The final
    line_2:        product will be spectra of flux vs. wavelength or velocity from which line
    line_3:        profiles, equivalent widths, central depths, and positions can be determined.
    line_4:        Rotational components, isotopic species and discrete velocity structures will
    line_5:        be identifiable.
    line_7:        The precise calibration and data reduction
    line_8:        techniques will be based on experience with two years of SV and other GTO
    line_9:        observations. Corrections to the data for diode array irregularities,
    line_10:       photocathode non-uniformities, Echelle ripple, optical vignetting, thermally
    line_11:       induced motion, ST doppler shifts etc. etc. will be optimized and applied.

  question:        9
    section:       1
    line_1:        This is an HRS team project. All members are involved in many GTO programs.

!

  question:        10
    section:       1
    line_1:        Computing facilities, software & programming support. research assistants,
    line_2:        manuscript preparation, publication support, travel expenses.
