[Comm2011] OCAM2 daily log day 3

[John P. McFarland]

Hi All,

Tonight was quite a productive night.  Unfortunately the Toelner is still 
not responding, so no new quick checks (despite the 51 test quick checks) or 
4-angle dome flats.  The problem will hopefully be solved today.  Andrea, 
Koen, and Dietrich arrived tonight and worked until around midnight when I 
took over.

The conditions were relatively good with mostly excellent 0.5-0.7 arcsec 
seeing, but somewhat poor transparency.  It is difficult to say which 
observations will be photometrically useful.  Several polar field 
observations were obtained, so the variable conditions should be seen there 
as well.  Complete 32 CCD offset observations in z and g were obtained for 
SA107.  These are almost perfect compared to the last nights' sets, but 
there was still some very light cirrus visible on the all-sky cam during 
these.  Also, please check the 32 CCDs exposures overlap for the center of 
the field.  The center was placed on all the CCDs in the order that they are 
stored in the RawFitsData.

A donut template was attempted for the VST people (requested by Koen), but 
failed due to some template keyword error (Andrea and Koen will have to 
investigate this).  Nonetheless, the focus offsets were done and the 
required data secured.

Following this, the night was wrapped up with a 3x3 grid from the newest 
plate system centered on about the SA113 field, taken with dither,N=5 in r 
for 60 seconds per exposure.  Please check these out to make sure all the 
offsets were done correctly.

Cheers,


-=John
