Helicity decoding fixes #488

Closed sawjlab closed 1 year ago

sawjlab commented 1 year ago

Two fixes that repair the ability to extract helicity information.

  1. TIBlobModule was occasionally not getting the TI event time. (See commit message). The TI time is needed to help predict the helicity.

  2. A FADC firmware change removed pulse data for channels with DC inputs (such as the helicity inputs.) Instead get the pedestal value from the first FADC sample.
