General Description

An imaging run in the NB 4.05 filter. The target is observed in two identical
 OB:s. Each OB contains a 0-33 deg pattern, with 19 jittering points at each rotation.

The brightest star in the field in both OB:s is Eps Ind with L' = 2.1 mag. This
 causes a significant saturation during observations (but not during acquisition,
 when neutral density filters are used). A waiver has been accepted for this, under
 the condition that 5 minutes are spent after each OB reading out the detector to
 get rid of memory artefacts (at the cost of science time, hence each OB is 1h 10
 min instead of 1h 15 min, see the 'waiver requests' section).

Waiver Requests

A waiver request for 1h 15min OB:s has been accepted.

A waiver request for saturating the detector has been accepted, under the condition
 that five minutes are spent reading out the detector after the execution of each
 OB, in order to get rid of memory effects. Hence, each OB contains 1h 10min of science
 time, after which five minutes should be continuously spent reading out the detector.

Critical Observing Condition Constraints

There are no critical oberving condition constraints associated with this
 run, beyond what is specified in the constraint set.

Time-Critical Aspects

As specified in the Phase I proposal, the observations should preferably
 be done in October (this is also obvious from the airmass toward Eps Ind during
 P82). Other than this, there are no time-critical aspects associated with this run.

If there are Finding Charts attached to your OBs, is the field-of-view of at least one of these charts 2' x 2' (with clearly labelled field orientation) ?

Have you clearly marked and labelled your wavefront reference objects R1, R2, R3, ... (as specified in the NAOS Preparation Software) on your Finding Charts ?

Have you specified the magnitude of the brightest object in the field-of-view for each OB ?

Are there objects in any of your fields (including standard stars) which are brighter than the limits specified in the User Manual and on NACO web Pages ?

If the previous answer is yes, have you given a list of OBs and a justification for the brightness limit violation in the general description field ?
