GS-2007A-DD-11-14-001 2007-07-10 23:00:17 Max of 20000 cnts. - OK
GS-2007A-DD-11-14-002 2007-07-10 23:03:40 Lines have low counts, in particular in the blue. Have to increase the exp. time by a factor of 4. - Usable
GS-2007A-DD-11-14-003 2007-07-10 23:06:30 As expected, the Ha line is saturated even with the 0.25arcsec slit and 1sec exposure.
GS-2007A-DD-11-14-004 2007-07-10 23:12:28 The star was moved slightly off the slit by +0.4" in P. The Ha line is nearly saturation (62000 cnts) and in the non-linear regime of the detector.
GS-2007A-DD-11-14-005 2007-07-10 23:18:37 An extra 0.3"offset applied to the slit (total 0.7" from the center.). Ha line is not saturated. Counts are below 50000 ADU. OK. DAS: it is still slightly saturated! Zooming into the Ha line you can see some saturation between y=[2304-2309]
GS-2007A-DD-11-14-006 2007-07-10 23:23:24 Extra arc with exp.time of 8sec. Looks ok.
