General Description

This is a simple imaging run with one image taken on 16 different positions
 and with all the same instrument setup (all with R band and with exposure time of
 15 seconds). The goal is to perform pre-imaging for an incoming VIMOS observation
 run. All the science OBs first point telescope to coordinates with suitable guide
 stars and then perform 1 exposure of 15 seconds.

The total exposure is 4 minutes and the execution of all our OBs, based on P2PP,
 will take 2 hours and 32 minutes. We are aware that this exceed the approved time
 of 0.6 hours for our program. Although we expect the observations to take less then
 2.533 hours, we are aware that any additional time needed then the 0.6 hours approved
 for pre-imaging will be subtracted from our spectroscopic follow-up run.

There is no OBs for calibration since it is not mandatory in PRE-IMAGING mode.

Critical Observing Condition Constraints

Observations needs to be done within +/- 2 hours from the meridian. Therefore,
 observations need to be done bellow and airmass of 1.20-1.25 for our targets (all
 our targets have declination from -50.6 to -54.4 degree).

The only other constraints are to have a seeing less then 1.2 arcsec, lunar illumination
 of less then 0.5 and Moon angular distance of 30 degree or more.

Time-Critical Aspects

There is no Time-Critical Aspects. However, as point out in Critical Observing
 Condition Constraints, observations needs to be done within +/- 2 hours from the
 meridian.

Special Execution Requirements

There is no Special Execution Requirements. However, as point out in Critical
 Observing Condition Constraints, observations needs to be done within +/- 2 hours
 from the meridian.

Special Calibration Information

There is no OBs for calibration since it is not mandatory in PRE-IMAGING
 mode. The calibration frames (bias, sky flats, and photometric standard star observation)
 will be delivered to us together with the pre-imaging data when the pre-imaging
 run will be completed.

Is this a Pre-imaging run ?

```
true

Pre-imaging Requirements

There is no Pre-imaging Requirements. However, as point out in Critical
 Observing Condition Constraints, observations needs to be done within +/- 2 hours
 from the meridian.

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 ?
