General Description

The purpose of these observations is to measure  or provide an upper limit
 for the sulphur abundance by using the SI lines at 1045nm, for star HE1327-2326.
 The OBs FS1..to FS7 are on top priority and should provide each S/N=80. FS8 is on
 low priority and should provide S/N=20. We are using standard setting 54/0/n, the
 radial velocity of the star is 68 km/s, all the three lines should fall on detector
 3 for any observation from January 2009 to March 2009. The vacuum wavelengths of
 the three lines are: 1045.8314nm, 1045.9622nm, 1046.2272nm.
There is a single OB for a telluric standard star, star HIP 66657, which should
 provide a S/N ratio of 800

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?

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?
