Estimated Total Execution Time (hours, including overheads)

```
2hours

General Description

This Run A consits in 7 VIMOS pre-imaging in the COSMOS 10+02 galaxy field
 to be follow-up with HR-red MOS 1arcsec slit spectroscopy. The spectroscopic observations
 will target galaxies brighter than I(AB)=22.5

Waiver Requests

No Waiver Request was submitted

Critical Observing Condition Constraints

Seeing should be kept below 1" since we will do HR-red MOS using 1" slits.

Time-Critical Aspects

This Run A should be executed as soon as the 10+02 field is observable,
 so that Run B can be prepared. Preparation of HR masks with tilted slits requires
 lots of time. Indeed we will use VMMPS and tilt the slits along the major ACS galaxy
 axis, and VMMPS do not handle this feature in an automatic way yet as it is the
 case for non-tilted slits.  
In resume, taking preimages as soon as possible will ensure us to prepare masks
 in good conditions.

Is this a Pre-imaging run ?

```
true

Pre-imaging Requirements

The User Priority ranges from 1 to 7 for the order of excecution of the
 7 pre-imaging.

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 ?
