 Description   

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.
