General Description

This program is aimed at detecting absorption features in the (rest-frame)
 optical
spectrum of a sample of BAL QSOs at various redshifts.
The list of targets includes three objects in addition to those listed in the
proposal. The inclusion of these new targets (specifically: SDSS1321-00, SDSS1302-00
and SDSS2109-06) was approved by ESO-USD through the request number USD-12446.

Waiver Requests

Critical Observing Condition Constraints

Seeing better than ~1.2 arcsec. Airmass lower than ~1.7.

Time-Critical Aspects

```
None
```

Special Execution Requirements

All targets should be detected clearly in the acquisition
images, and the slit should be centered directly on the target.
For some faint targets the slit is oriented to include
an "auxiliary ref. star" which will be used to check the alignment
of the spectra in the data reduction process; however these auxiliary
reference stars should possibly not be used for centering the slit, since
positioning the slit directly on the target is more accurate.
Please locate the target such that the auxiliary reference star is
also in the frame (see comment in each individual OB).

Higher priority should be given to the following three OBs:
S1605_K1, S1605_K2 and S1605_K3
