Far-UV Spectrometer Data


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

Time span: 1972-12-10 to 1975-12-19


This data set was provided by the experimenter and contains magnetic tape written on an IBM 7094 computer. Each 12-sec spectrometer scan is represented by a physical record containing 125 36-bit integer words. Record words numbered 6 to 120 are data words and represent the number of photoelectrons per 0.1 second, and the wavelength interval corresponding to each data word is identified. Calibration information is provided so that the outputs can be converted to brightness in rayleighs. Some of the parameters included in the aspect data are the distance to the Earth, right ascension and declination of the UV spectrometer's (UVS) optic axis, the angle between the UVS optics axis and Sun, the angle between the UVS optic axis and Earth, and the angle between the UVS optic axis and the Moon. The data are time ordered.
