Estimated Total Execution Time (hours, including overheads)

30:02
```

General Description

zCOSMOS OBs are for both bright masks (1x90 minute OB each) and "deep"
 masks (3x120 minute OB each, all identical, using the same mask, and called -part1,
 -part2 and -part3 ).   It would be good if the three OBs for each deep mask were
 completed before the next deep pointing is started.

Within the overall seeing constraint of < 1.20 arcsec, we would greatly appreciate
 it if you could please try to give preference within our program to doing the deep
 masks when the seeing is better, i.e. < 1 arcsec. This is an unoffical request
 based on the fact that zCOSMOS will use a lot of time that is better than the nominal
 seeing limit and follows discussions with Marina Rejkuba at ESO.

Please ensure daytime spectral flats are obtained for calibration.

Mar 7:  12 OBs submitted, totalling 24:26
Mar 8:   3 OBs submitted, totalling  5:36

This completes the nominal allocation of 30:00

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 ?

```
N/A
```

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 ?
