General Description

Medium Resolution spectroscopy of redshift >5.7 QSOs to search for
 intervening absorption lines

J0203+00: two wavelength settings, 8 identical OBs at 1034 nm and 2 identical OBs
 at 1070 nm
J1411+12: one wavelength setting, 10 identical OBs at 1034 nm

Experince during P78 visitor mode run showed that the QSOs should be visible at
 acquisition. However, they are quite faint, so to ensure the target is on the slit,
 the slit angle has been chosen to align with a nearby reference star.

The target coordinates are those of the nearby reference star. When acquired at
 the specified
slit angle, both the star and QSO will be on the slit.

The specified RA and Dec offsets are to be applied after the reference star has
 been acquired in the centre of the slit. These offsets will place the mid-point
 between reference star and QSO in the centre of the slit. After performing these
 offsets, the reference star will still be visible on the slit.

Waiver Requests

WaiverID:  079.A-0459A.01

The following waiver request has been granted (16/2/07) to have OBs longer than
 1 hour.

This program is a continuation of 079.A-256(A), which was carried out in visitor
 mode with
4*900 sec exposures. Since we will be adding the 078 and 079 spectra together it
 would be best if the individual exposure times were the same.

I understand that you cannot guarantee observing conditions for a longer OB, but
 are happy to take that chance to mantain consistent exposure times.
