General Description

This observing run is pre-imaging for follow-up VIMOS-MOS. We want to
 get rotation curves of disk galaxies in the supercluster A901/902 at redshift z=0.16.
 Four VIMOS pointings are necessary in total to cover a sky area of 30x30 arcmin^2.
 

The pre-imaging consists of four pointings with one OB per pointing. 
Each OB comprises 2 exposures of 140s in R-band. 
The four OBs are named:

PRE_sc901_sw.obx (South western pointing) - corresponding finding chart: 384.A-0813A.001.jpg
PRE_sc901_nw.obx (North western pointing) - corresponding finding chart: 384.A-0813A.003.jpg
PRE_sc901_se.obx (South eastern pointing) - corresponding finding chart: 384.A-0813A.002.jpg
PRE_sc901_ne.obx (North eastern pointing) - corresponding finding chart: 384.A-0813A.004.jpg

The exexution time is 15min per OB, totalling 60min.

Time-Critical Aspects

To ensure best visibility during the MOS observations, the pre-imaging
 should be taken in January 2010.

Is this a Pre-imaging run ?

```
true
```

Pre-imaging Requirements

```
None.
```

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 ?
