General Description

This is an imaging run for only one target (binary brown dwarf) in the
 Ks filter. In addition there is one OB for a PSF calibration star (we know that
 this star has a very faint companion, but the distance is far enough and will not
 affect our sience).
As well as an OB of a F8V+ G0V double star system, named "CAL_HD121325", which we
 will use as an astrometric calibrator for our science OB
In all OBs the bright object should be clearly visible during acquisition and should
 be centered in the array.

We use the IR wavefront sensor with the N90C10 dichroic. In all OBs the AO reference
 star = target. For Kelu1A the K-band magnitude is 12.35, for the PSF_calibr_star
 it is 9.96 mag and for the CAL_HD121325 K=5.08 mag (V=6.19 mag).
While the science OB (Kelu1) and the PSF calibration star OB consists of 9 and 8
 dither position on the targets, respectively, the OB of CAL_HD121325 consists of
 6 dither positions on the target and one dither position off the target with open
 loop for sky measurement.


PLEASE be also aware of the special calibration information (as described therein)!

Special Calibration Information

We added two calibration OBs to the science OB:
PSF_calib_star Ks_imaging_7 (for PSF calibration) and CAL_HD121325 (for astrometric/plate
 scale calibration). Please execute all three OBs in the contiguous order: science
 OB (Kelu1), PSF_calib and then CAL_HD121325.
Thank you very much for your cooperation!
