Previously undetected TOD artifacts found by visual inspection of the (preliminary) correlated noise map for the 44 GHz channel shown in the top panel. The middle and lower panels show a zoom-in of the source PIDs, namely PID 6144 (for the “triangle feature”) and PID 14 416 (for the “dashed stripe feature”). In the two latter, the black curve shows the TOD residual, d − s^tot, for each sample, and the red curve shows the same after boxcar averaging with a 1 s window.
