Installation: pip install -e git+ssh://[email protected]/nist_microcal/scan_server.git#egg=scan_server

A server to stand between a beamline (eg the spec computer at SSRL 10-1) and DASTARD/mass.

The beamline talks to ScanServer, ScanServer talks to Dastard and mass. Dastard writes OFF files. The TES must be already tuned, dastard must already have projectors loaded.

Intentions

Data Outputs

1. In real time, PFY_realtime comes from TESScanner.roi_get_counts via TESScanner._data 1.b. We could add a RIXS_realtime easily if a beamline system wanted it.
2. Immediatley after a scan, PFY_prelim and RIXS_prelim come from TESScanner.quick_post_process which relites on TESScanner._data. For example even if the dirft correction plan want a later calibration, just use the current calibration.
3. Sometime after a scan, PFY_final and RIXS final come from post_process, and may depend on calibrations that occur after the scan. This reprocessed from the off files and scan logs.

Perhaps beamline visualization will probably use 1 and/or 2. 3 is what the users take home, but
