Hi @tdietel
this is a first version of the DCS data point processing in O2. So far I am only taking into account the gas parameters and storing one CCDB object for them. Could you please have a look and see if it makes sense like that? I have to admit I tested it now only with a simulation. I am not sure that the format of the DCS data points is really the same in data. This I need to check probably with Denise.
In order to run the processing with a local CCDB:

  1. follow the instructions for a local instance here
  2. create CCDB entry with DCS data points by running Detectors/TRD/calibration/macros/makeTRDCCDBEntryForDCS.C
  3. start workflow
o2-calibration-trd-dcs-sim-workflow --max-timeframes 5 --delta-fraction 0.8 -b | o2-calibration-trd-dcs-workflow --use-ccdb-to-configure -b --use-verbose-mode | o2-calibration-ccdb-populator-workflow --ccdb-path="http://localhost:8080" -b

Cheers,
Ole

I have a few comments. The main one is the one around the converter. Do you want to test this before the merge?

I think DIM usually works with single precision float. Is the conversion to double intentional?

I have no idea about the precision of the data types.. All I have is the list from Denise. But if its usually single precision I'll use RAW_FLOAT instead

Ok, I guess we will see it in the tests.

- currently storing only information for the gas parameters (min/max/mean for defined period)
