XMM-Newton Data Files Handbook

7.1 Scientific Modes

For scientific exposures, instrument modes and filters are given with the fits header keywords SUBMODE and FILTER, respectively. These header keywords can be found in fits files of calibrated products (e.g., events files) and PPS files. As described above, the same names are used in the *SUM.SAS file. For the OM, there are only two instrument modes, IMAGE and FAST, which are indicated in the header keyword DATAMODE. Specific OM readout modes for IMAGE mode that affect the size and resolution can not be derived from header keywords nor file names. In Table 35 all scientific mode names and filter names are listed.
