    line_1:        WE PROPOSE TO USE THIS DIRECTOR'S DISCRETIONARY TIME TO
    line_2:        SEARCH FOR INTERSTELLAR ABSORPTION BY GASEOUS INTERSTELLAR
    line_3:        LEAD IN THE SPECTRUM OF 1 SCO. IN OUR CYCLE 1 DATA FROM
    line_4:        PROGRAM 3993, WE HAVE ALREADY SIMILARLY DETECTED INTER-
    line_5:        STELLAR TIN TOWARD THE SAME STAR. AT Z=50, TIN IS ONE OF
    line_6:        THE HEAVIEST ELEMENTS DETECTED IN THE INTERSTELLAR
    line_7:        MEDIUM, AND, AT Z=82, LEAD IS THE HEAVIEST. ON QUITE
    line_8:        FIRM GROUNDS, WE EXPECT THE 1433 A LINE OF PB II TO ATTAIN
    line_9:        A STRENGTH OF ABOUT 1 MA TOWARD 1 SCO, OR ABOUT 25% OF THAT
    line_10:       OF THE SN II 1400 A LINE WHICH WE HAVE PREVIOUSLY DETECTED.
    line_11:       SUCH A PB II LINE SHOULD BE DETECTABLE IN THE SINGLE
    line_12:       SPECTRAL EXPOSURE WHICH CONSTITUTES THIS PROGRAM.

  question:        3
    section:       1
    line_1:        FOR ONE STAR, ONE GHRS EXPOSURE IS TO BE OBTAINED THROUGH
    line_2:        THE LARGE SCIENCE APERTURE IN THE FP-SPLIT MODE, WITH THE
    line_3:        ECH-A GRATING. THE 4 SUB-EXPOSURES ARE CENTERED NEAR 1434 A.

  question:        4
    section:       1
    line_1:        THE PROPOSED SCIENTIFIC PROGRAM CANNOT BE CARRIED OUT WITH
    line_2:        ANY OTHER EXISTING TELESCOPE AND SPECTROGRAPH. THE HIGHEST
    line_3:        POSSIBLE SPECTRAL RESOLVING POWER AND S/N RATIO ARE REQUIRED
    line_4:        TO ACHIEVE A DETECTION OF THE EXPECTED VERY WEAK, NARROW
    line_5:        LINE.

!

  question:        5
    section:       1
    line_1:        THE EXPOSURE TIME REQURIED FOR THE ONE GHRS EXPOSURE IS GIVEN
    line_2:        BELOW IN THE EXPOSURE LOGSHEET. OBSERVED, ABSOLUTE FLUXES
    line_3:        MEASURED AT 1400 AND 1450 ANGSTROMS HAVE BEEN PUBLISHED FOR
    line_4:        1 SCO IN THE UV BRIGHT-STAR SPECTROPHOTOMETRIC CATALOGUE OF
    line_5:        CATALOGUE OF JAMAR ET AL (1976). THE ABSOLUTE SENSITIVITY OF
    line_6:        THE GHRS IS GIVEN IN THE GHRS INSTRUMENT HANDBOOK. THIS
    line_7:        COMBINATION ALLOWS STRAIGHTFORWARD ESTIMATES OF THE REQUIRED
    line_9:        EXPOSURE TIME.
