General Description

Multi-fibre observations of PMS stars in NGC 2264. The aims are to derive
 precise radial velocities and rotational velocities. This observing run consists
 of 4 target configurations, each of which is observed with 2 OBs (to fit inside
 the 1 hour rule). Each of the OBs consists of a 1 minute exposure with the ThAr
 lamp on (to get a good wavelength reference) followed by 2 longer exposures with
 the lamp OFF. Hence each target configuration ends up getting 4 exposures of 1280s.

Simultaneous UVES observations of a few bright, early-type stars will provide telluric
 correction.

Waiver Requests

082.C-0332A.01.WAV

We requested and were allowed to take the short exposure with the ThAr lamp on to
 allow simultaneous calibration of the GIRAFFE spectra, followed by longer target
 exposures with the lamp OFF.

We also have approved waivers to use Guide Stars that are just outside the 25 arcminute
 radius and to use attached nighttime flat fields. However, upon discussion with
 the support astronomer, we have decided not to do these.

Critical Observing Condition Constraints

```
CLR, seeing <= 1.0 arcsec
```

Time-Critical Aspects

```
None
```

Special Execution Requirements

```
None
```

Special Calibration Information

Note the short exposure at the beginning of each OB with the ThAr lamp
 ON, followed by 2 longer exposures with the ThAr lamp OFF. This is critical because
 we are working in the far red.

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 ?

```
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 in your OBs the hour angle range for which your Target Setup files are valid ?
