GN-2006A-Q-75-130-005 2006-04-08 12:05:18 peak=24653
GN-2006A-Q-75-130-006 2006-04-08 12:06:51 Changed to 3 x 10 sec coadds. Peak = 31594. Three of the five images in this repeated sequence have at least a few pixels above non-linearity (30000) so I have marked the whole observation USABLE and it will have to be repeated. But the images should be distributed because they can be useful to the PI maybe.
GN-2006A-Q-75-130-007 2006-04-08 12:07:34 Peak=24543, FWHM=0.126", looks quite round to me though (imexam contours).
GN-2006A-Q-75-130-008 2006-04-08 12:08:27 Peak=25331
GN-2006A-Q-75-130-009 2006-04-08 12:09:10 Peak=30665
GN-2006A-Q-75-130-010 2006-04-08 12:09:58 Peak=35384. NB Altair seeing dropped steadily over the course of these observations from about 0.8" with fluctuations as high as 0.96", ending up at about 0.65" at end of PSF star.
