omichain (omichain-1.74.10) [xmmsas_20230412_1735-21.0.0]

OPERATION

The following describes the way that an ODF is processed in the default mode. Figure 1 shows the overall operation of the omichain. It is split up into 3 separate pipelines:

• The tracking-history pipeline that processes the spacecraft tracking-history information for each exposure (as shown in Figure 2).

• The imaging pipline that processes the image from each exposure (as shown in Figure 3).

• The image-stacking and mosaicing pipeline that processes the mosaiced sky-images for each filter (as shown in Figure 4).
