This data set, on 35-mm black and white negatives, was copied from film supplied by the experimenter and contains 15 photographs of the Comet Kohoutek taken either in white light or with filters in both the ultraviolet and visible spectral regions, i.e., at wavelengths of 3581, 3090, and 4700 A. The film should be oriented so that the frame identification numbers (mission, film roll, and frame) are readable at the bottom of the frame when viewed. The film will then be as in the camera when viewed from the rear loading door. The emulsion side will be on the film side opposite the viewer, and the frame numbers will increase from right to left. Calibration details, tabulated frame numbers with filters used and operational chronology, an isophote plot of microdensitometer traces of the comet, and other details are included in the report distributed with the data. Microdensitometer scans of these frames were made, and the results were recorded on magnetic tape. Since the instructions for locating the comet and star images are too diverse and detailed to be recorded for general distribution, the desired tapes can be obtained directly from the experimenter. See Applied Optics, v. 16, no. 4, pp. 983-992, April 1977. The original flight film is kept at the Johnson Space Center.
