General Description

Using LGS + AO capabilities, we will estimate the orbit of 624 Hektor
 moonlet, a small satellite (6 km, corresponding to a Dm=4.2) orbiting at 1100 km
 (0.4") around a large elongated primary (2a=350 km, 2b=210 km -> Davg=280 km).
 Assuming a circular orbit, the period of revolution is estimated to 3-6 days. It
 is therefore necessary to take 1 observation per day ONLY, if possible at low airmass
 (<1.2) to maximize the chance of detecting the moonlet and over a small period
 of time (1-2 weeks).

The observation are relatively simple. Direct imaging in Ks band (less than 6 min
 of integration on the target). The target itself will be used as a tip-tilt star.
 It can be easily confirmed that you observe 624 Hektor (Trojan asteroid) since you
 should see its motion over 6 min of exposure.

We request 5 observations of the target. One observation of a PSF star will be use
 for deconvolution purpose and calibration. It should be taken briefly after or before
 one of the Target OB.

N/A
```

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

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

```
N/A

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_ ?

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 ?

```
N/A
```

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 ?
