GS-2005A-Q-2-25-001 2006-03-04 02:39:26 elongated PSF N-S along chop angle after closing astig loop. Most prominent elongation in first Dif image after nod then settles. Could be due to astig loop being closed and trying to correct during chop on neg image. DO NOT CHARGE FOR IMAGE 1. Repeated observation waiting for astig to settle then turning off and letting open loop model correct. Previous observations also did this. Only PSF image 1 affected by this.
