Thanks Sho, Yes… to be completely clear for Maurik, I believe those numbers are the angle of the SVT “hinge” relative to nominal. They go straight into the compact.xml in defining the detector geometry.

Is that just one channel or is it some way in which the status of all the channels is encoded? For the 2019 run, I do see cases where during a run one of the bias channels drops and recovers, while all the other channels are fine. >> >> Could you please help me decode this? >> >> Thanks, >> Maurik >> >> >> >> >> >> > > ######################################################################## > Use REPLY-ALL to reply to list > > To unsubscribe from the HPS-SOFTWARE list, click the following link: > https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
