General Description

This is a preimaging run for the spectroscopic VIMOS follow-up of the
 supercluster candidate XMMUJ0104.4-0630/XMMUJ0104.1-0635 at z~0.95. The main goal
 will be to investigate the galaxy populations of the two main clusters and to obtain
 redshift for 4 additional cluster candidates in the outskirts of the VIMOS field-of-view.
 The pre-imaging R-band data complements the existing NIR data of the field and extends
 the field coverage, i.e. the pre-imaging data will be very useful for the science
 analysis.

Two offset pointings are defined which overlap at the main cluster  XMMUJ0104.4-0630
 in order to increase the density of slits in this area.

Is this a Pre-imaging run ?

```
true
```

Pre-imaging Requirements

VIMOS pre-imaging is performed in the R band. Clear sky conditions in
 grey time with an average seeing will be enough to select spectroscopic targets.
 However, good sky conditions and a low sky background would greatly improve the
 value for scientific use of the pre-imaging data set.

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 ?

```
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
```

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 ?
