Estimated Total Execution Time (hours, including overheads)

```
1h 03mn 45s
```

General Description

Pre-imaging for 3 fields in the same general area.

Waiver Requests

No Waiver Request was submitted

Note that the total execution time for these 3 pre-imaging exposures is slightly
 above 1 hour due to the enormous overheads...these few minutes more should be recuperated
 back during the 9h of spectroscopic time in the next phase. It does not make sense
 to shorten the individual exposures below 10mn, the efficiency on sky would be too
 low...

Critical Observing Condition Constraints

No specific constraints other than those in the OB (photometric, seeing
 < 1"2, dark time)

Is this a Pre-imaging run ?

```
true
```

Pre-imaging Requirements

The airmass constraint (according to the  " 2hours around meridian" rule
 should be: AM < 1.25 (the set-up in P2PP does not allow more than one decimal....I
 have put 1.2, but one can thus go a bit further...)

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 ?
