Calibrated Individual Observations and CIO Pixel Index
The CIO files contain calibrated 1/8th second sampled sky survey data, in pixel number order, for each day of the cryogenic mission. In nearly all applications, the CIO can be thought of as a user-friendly version of the TOD. There are 285 CIO data files. Corresponding to each data file is a CIO Pixel Index file, which is designed to facilitate data retrieval (e.g., selection of time strings). All CIO files are FITS binary tables. The CIO files are on line. A typical data file is about 60 MB in size. To order the CIO data on CD-Rs or tape, contact the Request Coordination Office.
