Estimated Total Execution Time (hours, including overheads)
General Description
This is a simple spectroscopic programme which uses FLAMES in COMBINED
(UVES+MEDUSA) mode. The final aim of the programme is the determination of chemical
abundances in 5 Large Magellanic cloud clusters and surrounding fields by observing
a sample of giants
(V=16-17). The programme clusters are: NGC2108(priority=1), NGC 2157(priority=1),
NGC1806(priority=1), NGC 2257 (priority=1) and NGC2162 (priority=2).
We use UVES fibres to observe mainly cluster stars (normally 6 UVES fibres are allocated
on 6 stars in the central region of the cluster) and 2 UVES fibers are allocated
to the sky. MEDUSA fibers are used to sample stars in the field adjacent the cluster.
The execution time of each OB is a few seconds less than 1 hour. 7 or 8 OBs are
required to observe each cluster, usually the first 4 OBs use the following setup:UVES+MEDUSA
H572.8, the 3 additional OBs use UVES+MEDUSA H627.3, hence the stars observed with
MEDUSA fibers are observed in two setups. A total of 36 OBs have been submitted.
All the OBs have been checked for a period of 2 months (february and march) and
for a hour angle range of +/-4 hours.
Please note that guide and fiducial star magnitudes listed in the instrument file
ARE in K-band (typically the V-K colour for these stars is 2-4) hence any possible
warning of the system about excessive brightness of the guide and FACS can be negletted.
During the execution of the programme please take into account that we would prefer
to have a cluster completed (with all the 7 or 8 OBs done) before starting a new
cluster.

not part of the Calibration Plan ?
If you are observing Moving Targets, have you attached suitable ephemeris
files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
Did you specify in your OBs the hour angle range for which your Target
Setup files are valid ?
Did you specify in your OBs the magnitudes of FACBs and Guide Star for
all your fields ?
Are the FACBs and Guide Star in the brightness ranges specified in the
FLAMES manual ?
Did you enter the expected signal to noise in your OBs ?
