General Description

In may 2005 we observed a sample of ultracool dwarfs in Upper Scorpius
 with NACO to search for binaries.

We propose to obtain H and K photometry and H+K spectroscopy of the binary candidates
 in order to confirm the multiplicity.

For spectroscopy, the slit should be aligned with the axis of the binary in order
 to get the 2 spectra at the same time. PLEASE UPDATE THE P.A PROVIDED IN THE OB
 if you see that it is required to have the slit aligned with the axis of the binary
 ! Note also that the P.A we provide are given at +-180 degrees.

Note that 2 targets (USCO160121.5 & USCO160202.9) are triple systems, and that
 two sets of spectra should be obtained.

Objects are faint and red, and therefore challenging for NACO. If possible, the
 observations should be performed under very good and stable conditions.

For the spectroscopic OBs (*_spec), the finding chart was made with the NACO data
 obtained last year. 

The WFS reference targets are the same as the scientific or callibration targets.

The brightest objects in the fov are the targets themselves, with 9.6 < K <
 12.9 mag

Waiver Requests

- change the spectroscopic setting to S544SHK (077.D-0259A.01.WAV)

Critical Observing Condition Constraints

Objects are faint and red, and therefore challenging for NACO. They all
 could be observed last year with NACO under excellent conditions.

If possible, the observations should be performed under very good and stable conditions.

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 ?

```
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 ?

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 ?
