<div dir="ltr">Dear all<div><br></div><div>I would like to reiterate a call to individuals who intend to perform detector calibration, for a definition of skim information in the following form :</div><div><br></div><div>- a list of all the banks you need, ideally something like this : "RUN::rf","RUN::config", "TimeBasedTrkg::TBTracks", "ECAL::clusters", ...</div>
<div>- a condition on selecting events, ideally a list of consecutive cuts to apply to variables from specified bank variables. In principle this is quite arbitrary, and we can define as elaborated conditions for your skimming strategy as necessary</div><div><br></div><div>I will produce the skim files for you, using our golden runs, which will facilitate and unify the calibration process</div><div><br></div><div>Looking forward to your input</div><div><br></div><div>Best regards</div><div>FX</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jan 2, 2018 at 9:42 AM, Daniel Carman <span dir="ltr"><<a href="mailto:carman@jlab.org" target="_blank">carman@jlab.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="word-wrap:break-word">Folks,<div><br></div><div>Work is getting underway to revisit the CLAS12 Commissioning Plan to review what</div><div>steps have been fully (or sufficiently) completed, what steps were partially completed, </div><div>and what steps are still left to begin.
