General Description

Medium-resolution MOS spectroscopy of a z=0.54 cluster to obtain redshifts,
 membership and spectral properties for a sample of faint (R<24) 24um-selected
 sources in the region.  Two fields are targetted with total integration times of
 5hrs each (10*0.5hr) - slightly longer than the 4hrs requested in the Phase 1 -
 to account for the slight softening of the seeing limit and transparency over that
 requested in the Phase 1 (<1.2" instead of <1.0" and THN instead of CLR).
  The OBs are split into 4 groups: NE-high priority, NW-high priority, NE-low priority,
 NW-low priority (5 OBs each) to ensure even coverage of the exposure time on both
 fields.

Pre-imaging Requirements

```
N/A
```

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 ?
