J,H,K imaging of a region near the centre of Westerlund 1
to detect the low-mass end of the main sequence.
They run a generic offset pattern around a semi-bright star
and avoid the brightest objects in that region, which would
have saturated badly. This was a compromise found after the
program had been found unfeasible in the beginning.
Don't worry about the apparent mismatch in accuracy of the
offsets provided and the use of the Preset acquisition:
The offsets are just the result of a code and do not really
need to be anywhere near the specified precision.
