04:50 Did some major UI updates to merger /data02/2019data/dtas/scripts/parallelscript/runall_xe19_dev.sh
         If no parameters are passed, it asks to select each option one-by-one, showing available options
             For DTAS, if there is only one run for a given header, it automatically selects it
         After that, it checks that all the raw files actually exist
         Finally, it composes the command, asks the user if it looks OK, and then launches the script (or quits)
         (For experts, it can still take the original case where all 7 parameters are passed at the command line)
         There may still be some minor bugs, so for now we don't replace the original one until Alvaro can check

Alpha data used: /May19/{R1,R2,R7,R8,R9,R11} (c. 380 hr.)

Absolute calibration calculated with relative calibrated data

Data then resorted with absolute and relative gains applied

Attachment 1 -> Ey vs Ex plot for all detectors, with slope Ey=Ex show in red. Some non-linearity present, but to first order looks good

Attachment 2 -> Alpha peaks pre- absolute calibration in DSSD0
                Ex in blue, Ey in red
                To determine absolute calibration coefficients, assigned leading edge of higher energy peak an energy of 7.4 MeV (Uranium decay series)
                Divide this by the observed channel number (in keV) to get the absolute gain coefficients in keV/ch for Ex and Ey in each detector.
                (Note, data already offset corrected, pulser walkthrough)
                Values typically ~0.72 keV/ch
                Multiply appropriately by relative gains obtained from gainMatch.cpp to get final gain coefficients.
