[Rgc] [EXTERNAL] Re: analysis scripts

[mhattawy@odu.edu]

Hello Everyone,
  If you are doing analysis, you best use the dst bank schema files.
The recon dst files for the following list of runs can be found under
/volatile/clas12/rg-c/production/ana_data/dst/recon/
There are analysis skims for these runs ( edeutcut/ gmn/ jpsi/ sidisdvcs/
two/) can be found under
/volatile/clas12/rg-c/production/ana_data/dst/train/. The definition of the
different analysis skims can be found under
/work/clas12/rg-c/rgc-cooking/yaml/train_dst_20210109.yaml
and attached a screenshot of it.

List of cooked data in dst and analysis skims:
NH3-positive trg. pol. (270M triggers): 16327, 16328, 16329, 16330,
NH3-negative trg. pol.(160M triggers):16335, 16336, 16337, 16338,
C (250M triggers): 16290, 16291, 16292
ND3 (~500M triggers): 16277, 16279, 16280, 16281, 16283, 16284,
16285,16286, 16287, 16288,  016289

Best regards,
Mohammad.
