General Description

JHKL'-band imaging of young, compact star cluster. Primarily to determine
 frequency of circumstellar disks.

Brightest objects in the field have J=11.1mag, H=9.8mag or K=8.6mag, respectively,
 according to 2MASS, but when resolved with NACO into multiple sources they are faint
 enough individually to be away from saturation.
Please increase DIT in favour of NDIT for the OBs to be just below the non-linearity
 limit of the detector.

One OB is a multi-configuration OB with three filters (JHK), the other OB is just
 for L-band.
The FixedSkyOffset templates in the OBs serve to take a separate sky because the
 target region is very crowded.

Do all your OBs comply with the instrument-specific requirements listed on the instrument-specific Phase 2 web page ?

If this is a pre-imaging run, did you select PRE-IMAGING for the Observing Category for each Observing Template ?

```
N/A
```

Do all your finding charts comply with both the general and instrument-specific Phase 2 Web Pages ?

If you submitted OBs for standard stars, did you specify the magnitude and spectral type of all standard stars in the OBs ?

```
N/A
```

Have you included OBs for any calibrations that you need but which are not part of the Calibration Plan ?

```
N/A
```

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

```
N/A
```

If you have preferences which OBs should be executed first, did you make use of the User Priority field in the OBs ?

If this is a run that requires coordinated observations with other facilities, did you give proper instructions in the Time-Critical Aspects Section ?

```
N/A
```

If you have PSF reference star OBs, do the names of those OBs begin with PSF_ ?

```
N/A
```

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 ?
