21:50 Primary beam energy went up to 12.48 briefly and then back to 12.12 GeV. Starting a new run for HGTD anyway.
22:18 Stopped Run 198 to change DUT rotation angle to 130 deg. DUT rotation -10 RBV=131.24. Reconfigured twice to be sure to start Run 199. Correlations look good.
22:23 Noticed that each time we rotate and correlated hit region of DUT keeps on marching to higher X and the top edge is getting closer to the right edge. Since the top tip of the correlation diagonal line is running behind the histogram stat box, we tried to move the display stat box but that crashed the online Mon. Had to restart everything for new Run 200.
23:00 After the end of Run 200, we moved the DUT by -2.5mm (towards ESA gate - camera confirmed) to get away from the +x edge.
23:02 Started Run 201. X correlation moved left by the desired amount as expected.
23:14 The DUT correlation looked rather faint/low stat. Ending Run 201 early to reconfigure.
23:15 Started new Run 215 after double reconfig. Correlations looked better.
