Estimated Total Execution Time (hours, including overheads)

General Description

By these observations we want to study the chemical content of a large
 sample of stars of the various populations distributed on the SGB, RGB and HB in
 the Globular Cluster NGC 5139. The purpose is to enstablish a connection (via their
 metal content) between the different SGBs and RGBs, and the stars dispersed along
 the "flat" part of the HB.
To this aim we plan to observe our target stars with HR13 (7platesx4hr=28hr) and
 with HR04 set-up (5platesx1hr=5hr) for a total of 33hrs observing time.

Critical Observing Condition Constraints

We had the phase I proposal approved with a seeing <=1.0, 
airmass<=1.6, grey Moon, Moon 4 hours from our target, and clear sky.
Here we relaxed a bit our constrains asking for observations 
with seeing<=1.0, airmass<=1.6, Lunar illumination<=0.7 (3 days 
from the new moon), Moon angular distance>=60 degrees, 
and sky with thin cirrus or better.
