Skymaker for IR-filters
Hi all,

currently, I am trying to create a fits image with Skymaker according to an exposure of a galaxy cluster taken with HAWK-I@UT4 at Paranal in the Ks-filter. The parameters, Skymaker requires for the simulation are as follows:

CWL=2.146 microns
SEEING=0.93
BACKMAG=13
TEXPTIME=2880 s
MAGZP=27.2
GAIN=1.7
FULLWELL=50000
PIX_SCALE=0.106

My problem is, that due to the high skybackground, skymaker seems not able to create a fits image, as all pixels are saturated (in contrast to the real image). I tried to enlarge FULLWELL for several orders of magnitude, but nevertheless, only the brightest simulated objects such as large stars are visible.
Do you have any suggestions what I need to change in the parameters or is skymaker not able to produce fits-images in the IR?


cheers,

Jennifer Piel.

The truth is out there.
