General Description

VIMOS pre-imaging has been requested using the R filter in the surrounding
 10'x10' field of view of the central quasars HE1104-1805A and PKS0232-04. 
  The default 90 degrees rotator on sky will be used. This is to locate targets
 prior to a MOS follow-up in order to get spectroscopic redshifts of galaxies at
 z~1.
 These targets have already been selected using a colour cut from BRI imaging obtained
 during run
381.A-0874(A),(C).
  There will be 4x345 second exposures during this run. One 345 second image will
 be taken along one
line-of-sight before the pointing is moved 3.0'x3.0' in order to cover the VIMOS
 chip gap.
  THe same routine is then to be used when observing the 2nd quasar.

Waiver Requests

A request was made for these pre-imaging runs to be taken, however they
 were not requested during phase I
as it was assumed earlier VIMOS imaging runs would suffice.
The request was made on 29/07/08 with USD ticket number USD-24593.
This request was granted on 30/07/08. Given the short time until the deadline an
 extension was granted 
for phase II preparation until 7/08/08.

Pre-imaging Requirements

```
This is a pre-imaging run.
```

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 ?
