Dear CLAS12 detector subsystems Calibrators Group Leaders,
<p class="">RG-K is at the end of the pass2 calibration procedure.<br class="">
</p><p class="">You can find the latest RGK timelines at: <br class="">
</p><p class=""><a moz-do-not-send="true" href="https://clas12mon.jlab.org/rgk/pass0/v0.27/tlsummary/" class="moz-txt-link-freetext">https://clas12mon.jlab.org/rgk/pass0/v0.27/tlsummary/</a></p><p class=""><a moz-do-not-send="true" href="https://clas12mon.jlab.org/rgk/pass0/v0.27_qa/tlsummary/" class="moz-txt-link-freetext">https://clas12mon.jlab.org/rgk/pass0/v0.27_qa/tlsummary/</a><br class="">
</p><p class="">Please take a look at the obtained timelines, to validate the
quality of the calibration.</p><p class="">Should all of you be satisfied with the present results we could
assess the latest pass0 as the "final" one and proceed with the
Pass2 cooking review.</p><p class="">Please reply to my message at your earliest convenience.</p><p class="">For your info, the following table contains a description of the
different data taking conditions:</p>
