[Clas12_calcom] [EXTERNAL] RGA Fa18 mini timeline with updated tracking software

[L Smith]

Hi Timothy,

The fitted distributions look very close for ECAL timing and ‘ec gg mean’  although the actual fits are slightly different but negligible.  For SF the fitted distributions changed by +/- 0.3-0.7%, presumably caused by the denominator of E/P.  

Best regards,
Cole

We recently produced a mini timeline for the RGA Fa18 data set using this updated software but without any changes to the calibration. As far as I can tell, everything seems to have worked exactly as expected and no changes to the calibration quality are observed. However, I would be interested in and happy to receive a second opinion from each of the subsystem experts on the quality of their calibrations in this new timeline with coatjava 11.1.1. You would be comparing the final timeline before the ready-for-cooking review, rga_fa18_v0.26_qa <https://clas12mon.jlab.org/rga/pass2/fa18/pass0/rga_fa18_v0.26_qa/tlsummary/ >, with the new mini timeline using the DAF software, rga_fa18_v0.29_qa <https://clas12mon.jlab.org/rga/pass2/fa18/pass0/rga_fa18_v0.29_qa/tlsummary/ >. Please let me know your thoughts.
