Estimated Total Execution Time (hours, including overheads)

```
16hrs
```

General Description

Four pointings towards a possible z=0.5 supercluster. Objects for spectroscopy
 selected by R<23 and then to have colours of ellipticals or disk galaxies at
 0.3

Waiver Requests

083.A-0880B.01.WAV and 083.A-0880B.2.WAV  Both approved

These extend OBs to 1hr 20 mins to increase observing efficiency and to use the
 GG475 rather than OS-RED as the order sorting filter in order to extend the redshift
 range the Ca H+K and [OII] can be observed over. The mask design too this into account
 by specifying a short wavelength cut of 4500Angstroms rather than 5590 Angstroms.

Critical Observing Condition Constraints

```
None
```

Time-Critical Aspects

```
None
```

Special Execution Requirements

If possible, I would like the standard that we specified for our calib
 OB to be observed as part of the standard LR-RED+OS-RED calibration plan for that
 night. This would then give us a handle on the mapping between the two setups so
 that we can use the standards obtained on other nights our programme is observed
 through the OS-red to assess the variation in conditions between nights. If this
 does not happen, its not critical, it wouuld be useful though if it did happen.

Special Calibration Information

We have specified a single calib spectro-standard OB as we use a non-standard
  OS filter.

Is this a Pre-imaging run ?

```
false
```

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 ?

Have you included OBs for any calibrations that you need but which are not part of the Calibration Plan ?

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 ?
