not at same level as nnaida17. Is nnaida17 actually the problem? LH kapton PCB is the only

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

Maybe the issue was from looking at the details too often :)
07:46 Shift change.
DAQ continues running OK.
Statistics show noisy DSSD #1 (100-200kHz) - see attach 19
Tapeserver also shows higher than normal write to disk rate - see attach 20
After a few seconds write to disk rate goes back to normal - see attach 21
Data items rate looks OK (500k). This was checked after the rates in DSSD#1 went back to normal - see attach 22
FEE64 temperatures OK - see attach 23

System-wide checks OK except nnaida7 fails ADC calibration as usual.

Timewarp events appear to be very frequent, consistently every 3-5 seconds.

See LEC xy plot - attach 28
HEC xy plot shows no hints of issues - see attach 29
Rate seems manageable - see attach 30 for analysis of noisy run R2_103.
Note few seconds deadtime in some FEE64 and unequal number of Pause/Resume in nnaida 22
09:45 Rate in DSSD#1 back to normal. Data rate 500k, Write to disk 5 Mb/s.
10:00 Started compressing R2_* files to save disk space.
Used nice gzip to compress to avoid conflicts with the DAQ.

CA | Further tests of calibration on Alpha data | 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.
