GN-2006B-Q-84-18-001 2006-11-13 11:22:51 This first image suffers from the usual NIRI first image pattern. Definitely see spectra from both targets. Seeing was soft with excursions into IQ 85 territory especially during the first half of the observation. There also were several exposures with low level NIRI quadrant noise. I have added two repeats of the ABBA seqeunce to compensate for these effects.
GN-2006B-Q-84-18-010 2006-11-13 11:43:28 NIRI quadrant noise
GN-2006B-Q-84-18-014 2006-11-13 11:52:41 NIRI quadrant noise
GN-2006B-Q-84-18-015 2006-11-13 11:54:57 NIRI quadrant noise
GN-2006B-Q-84-18-016 2006-11-13 11:57:15 NIRI quadrant noise
GN-2006B-Q-84-18-019 2006-11-13 12:04:07 NIRI quadrant noise
GN-2006B-Q-84-18-023 2006-11-13 12:13:19 Now the guide signal is noticeably dropping because the seeing has significantly degraded again. I'll stop after this ABBA and take the flats, we'll have to come back on a better night to take some better data. Setting this one to usable because of the seeing
GN-2006B-Q-84-18-024 2006-11-13 12:15:39 Seeing bad, setting to usable. Spectral traces barely visible in image.
GN-2006B-Q-84-18-036 2006-11-14 12:03:52 Coming back to finish off this target, the seeing has been better and more stable tonight than during the first attempt. The seeing is at the high end of IQ 70 again for the first ABBA cycle but from the P2 seeing estimate the remaining images have better seeing.
GN-2006B-Q-84-18-042 2006-11-14 12:17:40 I definitely see spectral traces from both targets, I am surprised they are not stronger compared to the previous night given that the seeing is much better tonight, particularly for the last 8 images.
