GN-2005B-Q-16-132-001 2005-08-26 10:48:34 Where to put the slit??! Because the notes say the PI wants spectra along an axis I choose a point in the middle of the ring. Images 131 and 132 have the wrong instrument alignment angle. The offsets measured from image 133 are wrong, I suspect I had mistakenly used image 132 instead. 133: p=-5.52, q=+2.09, 134: p=+1.84, q=-3.48, 135: p=-0.31, 136: no more offsets, the slit should fall on or near a bright knot of emission on either side of the center. The slit center is drawn in my acquisition tool at an (x,y) pixel value of (189.5,104) and is drawn horizontal.
