[Lowq] DC Calibrations Update

[seema at jlab.org]

Hello Stepan,
Sorry for my delayed response! I have compiled the results of DC
calibration. Please have a look at the attached file DC_calib.pdf
Although we see many numbers red for superlayer 5 and 6 but we can't get
rid of these. Moreover these numbers are not too far off from the cut off
value say 310 microns for narrow sigmas in the code. So I think we can use
these constants for pass0 cooking. I made a list of the runs for different
energies:
(i) 60707 - 61210 (Ebeam = 5776 MeV)
Constants of run number 61107 which is very well calibrated will be
applied to this run range.
(ii) 61217 - 61481 (Ebeam = 1206 MeV)
Constants of run number 61440 to be copied.
(iii) 61483 - 61496 (Ebeam = 5776 MeV)
Constants of run number 61107 to be copied.
(iv) 61507 - 61782 (Ebeam = 6064MeV)
Constants of run number 61778 to be copied.
(v) 61787 - 61790 (Ebeam = 1269 MeV)
Constants of run number 61935 to be copied.
(vi)61791 - 61930 (Ebaem = 6064 MeV)
Constants of run number 61860 to be copied.
(vii) 61931-61972 (Ebeam = 1269 MeV)
Constants of run number 61935 to be copied.
If it's okay with you, I can go ahead and write these constants to the
appropriate run ranges.
Waiting for your reply,
Best regards,
Seema
