...
- DMCS connects to DM Event Services Broker and OCS
- Starts jobs on replicators, distributors and workers.
- Receives processing jobs from DMCS (one for each CCD and wavefront sensor)
- Receives archiving jobs from DMCS (one for each raft and one for WFS images)
- Jobs are distributed to worker machines
- Retrieve template image (by filter and airmass)
- Retrieve Objects from last Data Release
- Retrieve master calibration images
