This is a spectroscopic follow-up program consisting of one spectum carried
out each night during 17 nights. These measurements will allow to build
the radial velocity curve of the target, i.e the microquasar candidate
1RXSJ162848.1-415241.

LAST INFO about Time Critical Aspects:
With the distribution of measurements PI has in hands, and by considering
the ones carried out in October 2004, it is VERY important for PI to get
data between Feb 4. and Feb 7. !!


Time Critical Aspects (see README file for more details):
One spectrum carried out each night during 17 nights. In order to get
a good phase coverage, the whole program (the 17 measurements,
one per night) should be splitted into three different sequences.
 Sequ 1:  FEROS_seq1_objcal_1200-(0 to 8)  :  2004-10-01 to 2004-10-12
 Sequ 2:  FEROS_seq2_objcal_1200-(0 to 3)  :  2005-03-01 to 2005-03-05
 Sequ 3:  FEROS_seq3_objcal_1200-(0 to 3)  :  2005-03-25 to 2005-03-31

The target (1RXS J162848.1-415241) is not observable during the whole
period: i.e it is not visible from 2004 October 23th until 2005 February 01.
Thus, taken into account its observability as well
as the "P74 2p2 observational schedule", PI only consider Service Mode (SM)
and MPI nights since 2005 February 08.:


2005-02-08 (5 nights SM): start ~phase 0.75
    -> OK for observations (~same phase coverage than Sequ 3)
2005-03-05 to 2005-03-08: start ~phase 0
    -> OK for observations (~same phase coverage than Sequ 2)
2005-03-08 to 2005-03-15: start ~phase 0.6
    -> OK for observations (~same phase coverage than Sequ 1)
2005-03-17 to 2005-03-25: start ~phase 0.4
    -> OK for observations ()
2005-03-26 to 2005-03-31: start ~phase 0.85
    -> OK for observations (that is the Seq 3!)
