General Description

If possible we request observations as close to transit as possible.

We requested a waiver to saturate the detector heavily - this request was granted
 as NACO 281.D-5062A.01.WAV

We are looking to verify the existence of very faint extended structure emanating
 from the central star.   We expect the star to saturate very heavily (by a factor
 of 80) and the ghost images and latent images to remain several frames on.

We request that both of the NACO_img_acq_MoveToPixel sequences will position the
 central star on pixel 512, 512.

The two OBs comprising this programme are identical except for their position angles
 on the sky, which are +15 and -15 degrees.

In case of any queries please don't hesitate to phone Paul Hirst (+1 808 974 2630
 [office] or +1 808 987 2084 [mobile] on Hawaii time-zone) or Katherine Blundell
 (+44 1865 273308 [office] or +44 7930 240293 [mobile] on UK time-zone).  Our email
 addresses are: phirst@gemini.edu and kmb@astro.ox.ac.uk. 

Thank you very much.

Waiver Requests

Critical Observing Condition Constraints

```
Clear skies and good seeing.
```

Time-Critical Aspects

```
As near transit as possible.
```

Special Execution Requirements

Please position central star on position 512, 512 at acquisition.

Special Calibration Information

Please take darks and flats either before the observations, or when the
 array has recovered from being heavily saturated.

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_ ?

```
N/A
```

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 ?
