The counts maps typically include photons detected up to 40 degrees from the instrument axis. Most analysis has been done using data within 30 degrees of the instrument axis, where the point-spread function is narrower and the effective area greater than further off axis.
All files are in FITS format unless otherwise noted.
The various data product types are briefly summarized below. All of these observation-specific files are described in more detail below. The viewing period of the observation. E.g., viewing period 207.0 translates to a value of 2070 for this parameter. The date and time of the beginning of the observation.
