... The XMM Optical Monitor can produce data in two modes: Imaging and Fast (timing). The omgchain package reduces the OM Imaging mode data taken with either the UV or Optical grism filters (prism filters with diffraction gratings on the back which facilitate low-resolution spectroscopy). There are two filter positions of the filter wheel in front of the OM detector which are occupied by grisms (hereafter called grism-filters), one designed for the UV spectral range and another for the visual. ...
