[PIPE2D-957] look at flux variation over pfi wrt rotator angle

Fri, 13 Jan 2023 01:26:22 +0000

So after ~~PIPE2D-946~~ surprises, I took a look and compared the two pfilamps flat visits :

68351 exptime=600s insrot=180
69006 exptime=300s insrot=0

If you plot the extracted flux as a function of position and plot the ratio you can clearly see a pattern (see figure attached).

We have some sky data from the november run taken at various rotator angle(not all the range I'm afraid).
Try to see if there is indeed a consistent pattern.
