Estimated Total Execution Time (hours, including overheads)
General Description
This OB is for observing the S-stars in the Galactic Center with SINFONI.
It should be executed between July 18-19 and July 23-24 while the guest observers
of the runs 179.B-0261(D) and 179.B-0261(E) are still on the mountain. This agreement
was reached on May 4, 2007 see email exchange with Gautier Mathys below.
Dear Stefan, After consultation with Paranal Science Operations, it appears possible
to satisfy your request under the following conditions: the SINFONI SM OBs should
be accompanied with a prominent note in the README file stating that the observations
should be performed during the July nights when you will be on the mountain, in
some kind of VM assisted SM. The actual time slot when the observations would be
performed should be decided on the spot using standard OB selection procedure, and
you should be around so that the UT4 nighttime astronomer can get you at the console
within short notice. Based on this, I would propose to reduce the time allocation
of either of the NACO runs H and J from 4h to 2h, and to create a new SINFONI SM
run (Z), with a time allocation of 2h. Could you kindly confirm that this would
meet your needs, and let us know which of the NACO runs (H or J) we should shorten?

we were particularly unlucky. We just could not get what we have expected and what
would required only 2 hours of reasonable conditions: A cube of the central arcsecond
in order to determine the radial velocities of the stars orbiting the massive black
hole. Basically clouds have eaten up a lot of time, furthermore the seeing was too
bad and some more time was lost due to an earthquake. This will lead to an imbalance
between astrometry and radial velocity information for the orbital data. > >

from one of the two service mode runs which we have. > > Is this possible

Then we could think of scheduling these 2 hours for some time during the July NACO+VISIR
run. We have 6 half nights there. The GC is visible however the whole night. This
means that I (since I am the observer then) could just be in the control room the
whole night and in case the instruments scientist decides to do these observations,
I could assist him. > > What do you think? > > Best regards, > Stefan

Pre-imaging sources not listed above
Do all your OBs comply with the instrument-specific requirements listed
on the instrument-specific Phase 2 web page ?
If this is a pre-imaging run, did you select PRE-IMAGING for the Observing
Category for each Observing Template ?
Do all your finding charts comply with both the general and instrument-specific
Phase 2 Web Pages ?
If you submitted OBs for standard stars, did you specify the magnitude
and spectral type of all standard stars in the OBs ?
Have you included OBs for any calibrations that you need but which are
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 indicate the magnitude of the brightest object in the field in
each SINFONI OB?
If you are using the AO: Did you indicate for every OB the magnitude
of the guide star, and its distance to the target (if any)?
If you submitted OBs for standard stars, did you use the provided StandardStar
templates?
If you are using a specific offset pattern or position angle: did you
check carefully the definition in the manual?
Did you make really sure that none of your OBs ever saturates the detector?
If you are using the AO: did you enter the correct Strehl Ratio (on-axis,
K-band) AND the seeing value in the constraint set?
