General Description

This is a simple imaging run for only one target (binary brown dwarf)
 in the Ks filter. In addition there is an OB for a PSF calibration star (we know,
 that this star has a very faint companion, but the distance is fare enough and will
 not affect our sience). 
In both OBs the bright object should be clearly visible during acquisition and should
 be centered in the array. The K-band magnitude of the unresolved target Kelu1 was
 11.02, the resolved component of Kelu1A has a K-magnitude of 12.35
The K-band magnitude of the PSF_calib_star is 9.96

Please be also aware of the special time-critical aspects for this target! (As described
 therein)

Time-Critical Aspects

This observation is part of an ongoing monitoring program. The first observation
 in period P81 will be executed by ESO-ID 081.C-0340(A) in a specified time interval
 in the beginning of the period.
For this ESO-ID (381.C-0527(A)), which will be the continuation, we determined a
 later time interval from June 1st - July 31st.
Please be aware that we need a minimum epoch difference of 4-6 weeks between 2 observations
 to be able to measure an orbital movement of the binary. Therefore, we would like
 to ask you to cross-check at which date the OBs (309131 + 309133) for Kelu1 in 081.C-0340(A)
 were finally executed and then wait at least 4 weeks with this observation. 
Thank you very much for your cooperation!

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
```

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 ?

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

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 ?
