General Description

Imaging designed to obtain V,I photometry of brightest red giant stars
 in the outer halo of elliptical galaxy NGC 5128.  Three field locations are specified,
 in priority order.

Deep exposures under good seeing are necessary.

Waiver Requests

```
No Waiver Request was submitted
```

Critical Observing Condition Constraints

Darkest possible sky, photometric, high quality seeing

Time-Critical Aspects

```
None
```

Special Execution Requirements

Best possible seeing is required, MUST be 0.6 arcsec or less.

Finish the three fields in priority order.  Full data must be obtained for one field
 before going on to the next one.  Even completed field will be useful for the program.

I-band frames are taken with a 4-point dither pattern to help construct a fringe
 frame.

Pre-imaging Requirements

---(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
```

Did you specify suitable guide stars for all your OBs using Guidecam ?

Did you check that the chosen guide stars are suitable for all the offset positions and that they do not produce unacceptable vignetting of the field of view ?
