I am working on the ECAL library to see if I can find issues with the shower timing. Based on the recent change to HDGeant4 I already need to add a light propagation correction to the reconstruction.</div>

<div><span style="font-size: 13px;">On more issue that Simon pointed out to me. <br>
The ECAL timing is way off for all runs. It is around 6.6ns<br>
this is so far off that it barely fits into the monitoring histogram.<br>
I looked at two separate histograms and both yield the same result<br>
of a big offset:<br>
"HLDetectorTiming/Physics Triggers/TRACKING/ECAL - RF Time<br>
and:<br>
Independent/Hist_Neutrals/ECALNeutralShowerDeltaTVsE<br>
<br>
At this point I have no idea why the ECAL is so off.<br>

<div><span style="font-size: 13px;">Hi All,<br>
there are two runs where something did not go as planed.<br>
132705 and 133564, both these runs have hardly any statistics in the root files (at least the histogram<br>
I was looking at). However, both these runs are are over 1h long and have plenty of triggers.<br>
<br>

<p style="margin-top: 1em; margin-bottom: 1em;">Dear Colleagues,<br>
<br>
We completed another full monitoring launch for the 2025-01 GlueX-II data set. We successfully reconstructed 5 files for all 1197 runs with the RCDB query "@is_dirc_production and status!=0", for the first time with the correct material maps.</p>
<p style="margin-top: 1em; margin-bottom: 1em;">The usual monitoring plots can be found on the new PlotBrowser page:</p>

<br>
The REST files, trigger skims and several root trees, including PART trees for pi0, rho, omega and KLambda, are saved on cache:<br>
