General Description

Absorption spectra in four wavelength settings.

All science objects in this run are long period variables.
Due to this the magnitudes and colours given are only estimates.
The R and (B-R) may vary by one magnitude or more.
The R magnitudes are faint estimates, while the B-R colours are average estimates.

S/N are given for each individual wavelength setting and nod position.

The priorities are given under the assumption that priority 1 OBs are executed first.

Waiver Requests

 OB granted  on  Tue, 10 Jul 2007

Do the README file and the instrument comments of the telluric stars OBs include the required S/N/pixel of the spectrum of the telluric star, its spectral type and allowed spectral range?

Do any OBs include wavelength or flatfield calibrations?

```
N/A
```

If you are observing Moving Targets, have you attached suitable ephemeris files to your OBs?

```
N/A
```

If the slit viewer guide star is different from the target, are the RA and DEC offsets accurate to within 0.05 arcsec and do they take into account the relative proper motion between the two objects?

```
N/A
```

If you have preferences which OBs should be executed first for objects at similar RA, did you make use of the User Priority field in the OBs?
