GN-2006B-Q-39-95-001 2006-11-15 05:20:21 FWHM = 0.62", stars slightly elongated perhaps because we are looking directly into a light wind. This should not affect the quality of the spectroscopy. OFFSETS (arcsec): P = 0.49 Q = 1.15 ROTATION (deg) = -3.62, I am a bit suspicious about this large rotation.
GN-2006B-Q-39-95-003 2006-11-15 05:26:29 Looks pretty good but the rotation was too large. Estimating offsets by eye since the seeing is good enough to allow. Rotation = +3deg, P = -0.1
GN-2006B-Q-39-95-004 2006-11-15 05:30:08 Rotation looks good, taking out the small poffset: P = +0.1
