General Description

This is an imaging run for only one target (binary brown dwarf) in the
 Ks filter. In addition there is an 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).
In both OBs the bright object should be clearly visible during acquisition and should
 be centered in the array. We will performe the acquisition with the S13 camera,
 while the imaging starts with the S13 camera, we will change it to the S27 camera
 later on during the same OB without re-acquisition to keep the same/similar AO performence.
 Since the target will be placed in the center of the S13 camera after the last dither
 point, the target should still be fairly centered after changing to S27. The same
 principle will be performed for the PSF_star.

We use the IR wavefront sensor with the N90C10 dichroic. In both OBs the AO reference
 star = target. For Kelu1A the K-band magnitude is 12.35, and for the PSF_calibr_star
 it is 9.96.
