General Description

This is a pre-imaging run to get the correct positions of stars of interest
 (variable sources, X-ray-sources) for MOS-spectroscopy. To cover the FOV of the
 ESO-WFI, we have 4 adjacent pointings for each field (Ridge1 = PRE_SHIVA_2_X, Ridge3
 = PRE_SHIVA_3_X, and Ridge4 = PRE_SHIVA_4_X).

Waiver Requests

We submitted a request (not as a waiver, but to usd-help@eso.org) on Tue,
 06 Feb 2007. In this we asked to shift a small amount of observing time (16 min)
 from run 079.D-0280(B) (MOS) to this run (079.D-0280(A), pre-imaging), because we
 did an erroneous execution-time estimation in the proposal.
This request was approved by mail: 
  Subject: Support Request Number USD-18653 is now CLOSED
  Date: Tue, 6 Feb 2007 18:13:45 +0100 (MET)

We will now spend 2:16 h for the pre-imaging, and 10:44 h for the MOS.

Is this a Pre-imaging run ?

```
true
```

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 ?

```
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 ?
