General Description

Dynamics of the young cluster NGC3603
-------------------------------------

In this program we aim to determine the velocity dispersion profile for stars in
 the young (1 Myr) galactic star cluster NGC3603. Due to crowding, the inner 2 core
 radii are mosaiced with 11 pointings of the ARGUS IFU on FLAMES. Due to high reddening
 a red grating (L881.7) is chosen. Radial velocities will be determined from the
 CaT (for cool stars) and from the Paschen lines for the hot stars. Goal is to go
 down to spectral type A. During each ARGUS exposure, simultaneous observations with
 7 UVES fibres (+1 UVES fibre for sky) are taken of stars outside the inner 2 core
 radii. A similar grating as for ARGUS is used for UVES (860). 

From the velocities dynamical signatures of mass segregation and cluster expansion
 will be studied. 


The 11 ARGUS pointings are numbered and oriented as follows ("|" = long axis NS
 and "-" is long axis EW):


 -  | -           01  11  02
 
| | | | |   =>  03 04 05 06 07

 -  | -           08  10  09

with 05 on the core of the cluster. For the pointings 01/02/08 and 09 the ARGUS
 angle is 90 degrees. For the others (03/04/05/06/07/10 and 11) the ARGUS angle is
 0 degrees. For all OBs the ARGUS scale 1:1 is used.
