General Description

Pre-imaging to be done at the earliest convenience for MOS programme in
 P81; conditions: within 2 hours of culmination, grey time, THN, <=0.8" seeing.

This is standard pre-imaing for a VIMOS MOS run of an area of sky surrounding a
 high-z galaxy cluser which is covered in four pointings: Pointing 1 (SE of cluster
 centre), Pointing 2 (NE of cluster centre), Pointing 3 (SW of cluster centre), &
 Pointing 4 (NW of cluster centre). 

I have chosen guide stars with limited vignetting.  If other guide stars need to
 be used on the night, please try to limit vignetting in the central region of the
 overall field as we are particularly keen to target sources in this region.  (I.e.
 please try NOT to allow vignetting in the NW corner of Pointing 1, SW corner of
 Pointing 2, NE corner of Pointing 3, and SE corner of Pointing 4.)

Pre-imaging Requirements

Pre-imaging to be done at the earliest convenience for MOS programme in
 P81; conditions: within 2 hours of culmination, grey time, THN, <=0.8" seeing.

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 ?

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 ?
