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. |
