General Description

An SDI+ imaging run with ADI, taking images at several different rotator
 angles. The detector is expected to saturate by a modest factor at the center of
 the primary star, as is usually done for NACO-SDI+ observations to optimize the
 SNR over the whole image range.

This AO observation is performed in NGS mode, using the VIS dichroic. The NGS is
 HIP 25283 itself, which has a visual brightness of V=9 mag.

The brightest object in the FOV is HIP 25283 itself, with H=6.1 mag.

If possible, please direct any communication about the OB to Markus Janson (janson@mpia.de)
 in addition to the PI (lenzen@mpia.de).

Waiver Requests

A request to observe HIP 25283, which was not part of the original proposal,
 has been accepted.

A waiver request to use a 1.5h OB was accepted, under the condition that if the
 conditions degrade below specifications after 1h, the observations are not aborted
 or repeated.

Critical Observing Condition Constraints

There are no critical observing conidition constraints associated with
 this run, beyond what is specified in the OB itself.

Time-Critical Aspects

There are no time-critical aspects associated with this run.
