[Eg6_analysis] [Lowq] DC Calibrations Update

[seema at jlab.org]

Hi Lamiaa,
Thanks for your suggestions! I can use the same partition for DC
calibration constants. But I didn't calibrate run numbers 61535 and 61790.
So what to do with these two run ranges to start pass0? I can calibrate
these runs by the end of this week because each run requires 4-5
iterations. Also could you please submit jobs for these two runs?
Best regards,
Seema
