Abstract for MTS:
AO assisted K-observations of different selected regions in NGC 3603 for different purposes. The high-spatial-resolution observations are of the cluster core region, the others a bit further (few arcsec) away. Some of the OBs ("core" and "red") contain
a mosaicking offset pattern. See FC for details.
They require good seeing (<=0.6") to be able to lock on the AO star, which is none of the central stars, but the one slightly off-centre. Nevertheless, it is required to stop down the aperture to 1". This is the acquisition strategy outlined by Thomas:
ACQUISITION=
Preset about to the suggested guide star=
Center the suggested guide star and close the loop (this will be unstable
due to the proximity of the core of NGC 3603.
Open loop, changes diaphragm size to 1" and close loop.
Fine center the guide star on 250 and 25mas scales
Please, mind user priorities!
