Estimated Total Execution Time (hours, including overheads)

16h

General Description

The aim of this programme is to obtain high-resolution and high S/N spectra
 of 2 extremely metal-poor stars using the very good sensitivity of UVES in the UV.
 We will use these spectra to measure abundances of intermediate-mass neutron-capture
 elements in order to confirm the existence of the so-called "weak" r-process.

There are no priorities for the OBs and no time constraints, ie OBs may be executed
 at any time. Since the OBs are longer than 1 hour, we are aware that they will not
 be repeated if the weather classification changes after the first hour.

We did not submit any finding charts because the targets are very easy to identify
 (brightest object in the center of the UVES field of view).

Waiver Requests

A waiver request was accepted on 2008-01-31 for OBs exceeding 1hr (WaiverID:
  081.D-0426A.01), with the usual restriction that if the conditions degrade in violation
 of the constraints after the first hour, the OB will not be repeated.
