This is a document for <br>discussion and feedback is welcome. The goal, after we have hashed it <br>out, is to have precise definitions of all constants that are placed in <br>the calibrations data base. In particular, it is necessary to choose <br>some conventions, which need to be clear to avoid errors in <br>reconstruction. We need to agree on what those conventions are. We <br>should also make sure that there are no factors of 2 missing.<br><br>The document proposes that the gains be specified at the center of the <br>module. If I understand correctly, this is different than Andrei's <br>convention that uses the end of the module.<br>Therefore, there is a factor of e^{-L/2*lambda} between the two that <br>needs to be sorted out. There may also be other definitions or <br>conventions that need consensus.<br><br>We should probably find a dedicated time to go over this. As we are in <br>the process of entering constants into db now, I would hope to have a <br>discussion soon. Is Friday a possibility?<br><br>Thanks, Elton.<br><br><br>-- <br>Elton Smith<br>Jefferson Lab MS 12H3<br>12000 Jefferson Ave STE 4<br>Newport News, VA 23606<br>(757) 269-7625<br>(757) 269-6331 fax<br><br>_______________________________________________<br>Halld-cal mailing list<br><a href="mailto:Halld-cal@jlab.org">Halld-cal@jlab.org</a><br>https://mailman.jlab.org/mailman/listinfo/halld-cal<br></blockquote></div><br><div apple-content-edited="true">
