Far-Ultraviolet Spectrometer Data on Microfilm

NSSDCA ID: PSPA-00203

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1972-12-10 to 1972-12-19

Description

This 16-mm film data set was supplied by the experimenter and displays graphically some of the data contained in the tape data set 72-096A-02A. The data are not in temporal order. They are displayed in two forms -- averages of the spectra, and time variations in the intensities observed at the following wavelengths -- 1216, 1275, 1304, 1470, 1556, and 1657 A. The frames showing spectra are labeled identifying the five spectra used in the display and the actual elapsed time in hours, minutes, and seconds of the first spectra. The ordinate shows average counts per bin, and the abscissa displays bin number (wave-length interval). The counts shown are the average over 5 spectra. The average counts/bin value can be converted to brightness in rayleighs. The time-variation plots show the brightness in rayleighs (ordinate) as a function of actual elapsed time expressed in decimal hours. Each framed here covers 1 hr of data, and has the wavelength of the measurement printed. The accompanying aspect data contains values for several parameters including right ascension and declination of the UV spectrometer (UVS) optic axis, distance to the earth, the angle between the UVS optic axis and the sun, the angle between the UVS optic axis and earth, and the angle between the UVS optic axis and the moon.

Digital images (scans) of the entire contents of the microfilm are available as data collection PSPA-00610.
