[Clas12_first_exp] Accelerator status/Hall access/cosmic, calibration runs/meeting today at 3pm

[Francois-Xavier Girod]

Dear Mac

We have data on the same place as usual on volatile
/volatile/clas12/data/rg-a/current
As the name suggests, these data keep changing

We have created a more stable directory for the purpose of calibration
before pass0 here
/work/clas12/clas12/data/calib/cooked

The runs we selected for calibration at the moment are
3083
3820
3842
3938
4013
4150

We are also testing a couple 2 GeV runs at
/work/clas12/clas12/data/calib/torusMapMay8th_cooked

Best regards
FX
