    • 5 km at the comet. Image motion tests at the end of the night through one telescope indicated that the seeing was 0.9-arc-sec FWHM. However, the combined beam of the ensemble of telescopes and spectrograph optics yielded stellar images 2 to 3 arc sec FWHM and 6 to 7 arc sec full-width at zero intensity so there was loss of light from the standard calibration stars through the 1-arc-sec-wide slit. The transparency of the sky was excellent during our observations.

    • The reflectance spectrum was derived by dividing the spectrum of the comet by the spectrum of the solar analog star and then normalized to unity at 5500 Å.
