omgchain (omgchain-1.12.1) [xmmsas_20211130_0941-20.0.0]
Grism chain procedure
employs seven SAS tasks (Fig.1).
The first four tasks are preparatory. For instance, if the
OSW image is split into sub-windows, then these sub-windows are combined
into a single file (see section 4.1).
The necessary keywords, if missed, are inserted into the
file headers. These tasks also implement the above-mentioned corrections
to the image.

The other three tasks execute the source detection and spectral
identification procedure, and produce corresponding output.
