General Description

This program aims at taking stellar spectra of horizontal branch (HB)
 stars in the globular cluster NGC5927 and simultaneously take spectra of turn off
 (TO) stars in the same cluster. The main targets have been identified using images
 taken with ACS on board HST. In addition to these targets we have identified possible
 red giants and/or HB stars in the outer parts of the cluster using the 2MASS catalogue.
 The HB stars identified on the ACS image are observed using UVES and all the other
 are observed using MEDUSA fibres. 
All coordinates in the target list are based on the 2MASS coordinate system. 
The magnitudes of the HB stars in V is around 16.5-17. The TO stars have V around
 20.
The HA has been checked for +/- 6 hours for nights in May, June, July, and August.
 There were no conflicts.

Waiver Requests

A waiver request was submitted and approved: WaiverID:  079.B-0721A.01

The request has been approved. In summary we are allowed to exceed the normal OB
 time
and expose for 1 (one) hour per target and add the OH time on top of that. Full
 OBs
are hence about one hour and fourteen minutes.
