00README.TXT for the data from the EUV spectrometer on the STP 78-1 satellite This investigation used an Extreme UltraViolet (EUV) spectrograph to measure airglow radiation in the upper atmosphere. The instrument had a 6- by 6-degree field of view and covered the 200 Angstrom to 1300 Angstrom spectral region with selectable 5 or 10 Angstrom resolution. The data are in binary format and cover the time period from March 1979 to March 1980 with occasional data gaps. Details of the instrument, the data format, the given parameters are provided on the web pages available at the DOCUMENTS link (http://spdf.gsfc.nasa.gov/pub/data/stp78-1/euvs_airglow/documents/). The data were provided by Tim Cook and Supriya Chakrabarti of the University of Massachusetts Lowell.
