Patterns in Plotting

During the last testbeam we observed some patterns in the plotted maps for ITk. There seems to be a shift in the plotted pixel location along the matrix diagonal. This already appears in the RD53B icon on the title page. What makes this even more interesting, the pattern for the occupancy map only appeared for short data taking periods in the order of seconds to minutes.20240712_205455_ext_trigger_scan_interpreted.pdf Once a threshold of hits was reached, the occupancy map showed the expected beam spot. 20240709_161854_ext_trigger_scan_interpreted.pdf
