If I have a RawCalorimeterHit object, and I want the corresponding channel’s unique channel_id from the database. I came up with this that seems to work (in that it looks like it’s always between 0 and 441, but I didn’t check it any more than that): findChannel(hit.getCellID()).getCalibration().getChannelId() Does anyone know if it is correct? -Nathan ######################################################################## 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
