This file provides documentation for files 31-40, which contain count rate data from the ten flights included in the Wisconsin all-sky survey of the soft X-ray diffuse background. These are the data that were used to create the maps presented in McCammon et al. (1983) and contained in files 3-28 of this tape. If you intend to use these data to produce maps of the soft X-ray background, please note that these files contain rates and errors for each energy band, whereas the maps presented in McCammon et al. were made by casting counts and livetimes onto separate maps and dividing them to get an intensity map. The rates and errors in these files should be converted to counts and livetimes before being cast into maps. There are ten flights in the survey. The scan paths of the ten flights are plotted in McCammon et al. (1983) for zenith angles less than 90 degrees. Each file contains up to 1451 observations for one flight, encoded as 8 bit ASCII characters. Each physical record contains 2560 characters. Each logical record contains 80 characters. The first logical record in each file is a header record identifying the file, written in (A80) format. Succeeding logical records contain the observations, with five consecutive logical records per observation. Each observation consists of the data taken during a 0.2 second time interval, during which the payload scanned at most about 1.1 degrees. The data for each observation consist of aspect information for the observation plus rates, errors and atmospheric transmissions for the energy bands: B, C, M, M1, M2, I, J and 2-6. The rates given here are corrected for detector livetime, non-X-ray background and atmospheric transmission and are normalized to flight 13.103. For each observation, the rate and error for any band were set to -99.0 if the livetime for that band was less than 0.02 sec, or if the atmospheric transmission for that band was less than 0.8. The information for each observation is arranged as follows: FLIGHT: (0PF10.3 format) - Flight number of this flight. MIN: (I10 format) - Minutes past the hour for the center of the 0.2 second observation. SEC: (0PF10.2 format) - Seconds past the minute for the center of the 0.2 second observation. Flag word: (4X,O6 format) - Only the least significant 16 bits are used. They contain the following information (bits numbered 1-16 from left to right): 1: set to 1 if the observation contains bad telemetry. 2: set to 1 if there are fewer than 50 useful telemetry subframes in the observation (each observation can contain a maximum of 125 subframes for flights 13.083 and 13.102, or 250 for the other flights). 3: set to 1 if the livetime correction is uncertain. 5: set to 1 if the B and/or C band data are definitely contaminated. 6: set to 1 if the B and/or C band data are possibly contaminated. 10: set to 1 if the payload was pointed at the Earth. 11: set to 1 if a B and/or C band source was in the field of view. These are: HZ43, Am Her, the Cygnus Loop, Vela-Puppis SNR's, Sco X-1, and U Gem. 12: set to 1 if the M and/or I band data show evidence for the presence of a source in the field of view. 13: set to 1 if the J and/or 2-6 band data show evidence for the presence of a source in the field of view. 14: set to 1 if the following sources are in the field of view: Sources listed in the 4-th Uhuru catalog with >= 20 4U cps. Vela-Puppis SNR's. Cygnus Loop. Example: The flag word of the first record of file 31 (13.083) is written as: 004000, indicating that bit 5 is set because the B and C band data for that observation are known to be contaminated. Note that records were not cast onto the maps presented in McCammon et al. (1983) if the following flags were set: For the B and C bands: 1, 2, 3, 5, 10, 11 For the M1 through 2-6 bands: 1, 2, 3, 10, 14 GLONG: (1PE10.3E2 format) - Galactic longitude of the center of the field of view for this observation, in degrees.
