General Description

General Overview
----------------
High resolution spectroscopy of a R = 19.5 QSO at redshift z = 2.572

Standard UVES setting 390+564 (DIC-1). After low signal has been detected in blue
 spectra with our original 3200s integrations (email from 04.10.05), we followed
 recommendation by PSO to use exposure times up to 5400s. Therefore, number of remaining
 OBs is now reduced to 9 (from 14 that were left), each of them with 5320s integrations.
 

QSO should be visible at acquisition. 
Should the observer experience any difficulties at acquisition,
it is also possible to offset from a nearby star (indicated on the
finding chart).

The coordinates of the offset star are (J2000)

RA:  23:46:25.31
Dec: 12:47:26.83

From this reference star, offset 1.46 arcsec E and 17.04 arcsec N
to reach the QSO.

All the observations are to be conducted with the slit vertical
on the sky

Waiver Requests

I have submitted a request to waive the restriction
that OBs should not last longer than 1 hour.
Each of my OBs lasts 1:03:15 with an integration time of
3200 s. Given the faintness of the QSO, I consider this to
be the best observing strategy.
