Wilkinson Microwave Anisotropy Probe
Time-Ordered Data (archive with attitude, etc.)
Three complete time-ordered data archives are supplied with the last WMAP data release; two contain calibrated data while the third contains uncalibrated (or raw) data. The uncalibrated archive contains all four radiometer channels for each observation. One calibrated archive has been coadded into two radiometer channels to reduce their size while the other contains all four radiometer channels.
This data are provided through a set of compressed tar files. Each tar file contains twenty files; each of these files contains one day of WMAP data written in five binary FITS tables. These tables contain:
For a far more complete description of the time-ordered data and these files, see the WMAP Explanatory Supplement. A sample of each FITS header is available here. IDL routines to read this product are available from the WMAP Software page.
