General Description

AO imaging of Pluto occultation stars to determine if they are single
 or not, as this affects the astrometry of the occultation.

OB PSF_P445.3 (object P240.1) is the PSF star for P445.3.

The target should be placed roughly near the center of the field after acqisition.

If P438 or P435 (or both) are observed on the same night as P445.3/PSF_P445.3, they
 will benefit from sharing the PSF.

Within a 2' x 2' field, the brightest V, J, and K magnitudes are
         V    J    K
P240.1 12.3 10.5  9.7
P445.3 11.7 10.3  9.8
P438   13.3 10.4  9.1
P435   12.8 10.7  9.7

Critical Observing Condition Constraints

Variable, thin cirrus. 0.8" seeing, airmass < 1.2.  Full lunar illumination,
 more than 30 deg from target.

Time-Critical Aspects

None.

I think some of the OB for run B have the time span checked by mistake.

Source(s) of Pre-imaging

---(Empty)---

Pre-imaging sources not listed above

---(Empty)---

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_ ?

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 ?
