General Description

This programme aims at photometry of the intermediate and low-mass cluster
 members of a young starburst cluster.
3 pointings are observed in H,Ks and L using the IR WFS.

The observations sequence is as follows:

1) aquisition with centering on a bright star in the field (NOTE: if this star is
 not visible in L, the interactive centering could be skipped)

2) Offset to a skyfield with a 5 point jitter pattern

3) offset back to the science field: 2 times a 9 point jitter pattern

4) offset to sky field: 5 point jitter pattern.


For the H and Ks: the IR WFS N90C10 is used, while for the L-band observations the
 JHK WFS is used.
Please make sure that the photometric standard stars are also observed in those
 dicroics.

For the OBS SCI_10049center_H, Ks and L, three AO stars are indicated. The best
 star (R3) is within ~2.5 arcsec of an other star with about the same magnitude.
 If the seeing is good and stable, this star is prefered for as a AO reference star.
 Otherwise, please use them in the order given.


For the NAOS acquisition of the central field in the cluster it might be difficult
 to find a proper sky for the Field selector, the following offset could be used
 for the following OBS:

SCI_10049center_H, SCI_10049center_Ks, SCI_10049center_L:


R1: 
delta ra: 5.5 arcsec
delta dec: 16.5 arcsec

R2:
delta ra: -7 arcsec
delta dec: 20 arcsec

R3: 
delta ra: -14 arcsec
delta dec: 26 arcsec

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 ?
