We have only seen this in one run (10591), but are just starting to check others. The files where this is missing will fall back on 26 samples. It becomes a question of if you’d prefer the correct result when available, or a consistent result across all runs with the incorrect values. Since you changed the values in the config files, this won’t be a problem in the future.<div><span class=""> <br><div>

For the BCAL, the configuration file had NSB = 0 and NSA=26, FCAL, NSB = 0 and NSA=15, so we were subtracting off 26 and 15 samples of pedestal, respectively. In reality, on the flash NSB was being forced to 1. The new code will correctly subtract 27 and 16 samples from the BCAL/FCAL by grabbing these values from the registers. This will obviously cause some small shift in the energy calibrations.<br><br>If you think I should just pull the fix into the master branch, let me know.<br><br>--<br>Michael Staib<br>Graduate Student, Dept. of Physics<br>Carnegie Mellon University<br><a href="mailto:mstaib@cmu.edu" target="_blank">mstaib@cmu.edu</a><br>phone: <a href="tel:412-268-2983" value="+14122682983" target="_blank">412-268-2983</a><br><br><br><br><br>_______________________________________________<br>Halld-cal mailing list<br><a href="mailto:Halld-cal@jlab.org" target="_blank">Halld-cal@jlab.org</a><br><a href="https://mailman.jlab.org/mailman/listinfo/halld-cal" target="_blank">https://mailman.jlab.org/mailman/listinfo/halld-cal</a><br></div></div></blockquote></div><br></div></div></div></blockquote></div><br></div></div></div></div></div><br>_______________________________________________<br>
