Estimated Total Execution Time (hours, including overheads)
General Description
The goal of the observation is to obtain J, H, and K-band images of EX
Lupi, with 4 different position angles to perform two-dimensional spectroastrometry.
We will obtaine images at 3 bands at J, H, and K at one position angle, and then
repeat the procedure another 3 times for P.A.=180/90/270. This plan however costs
4 times of telescope pre-set and theacquision, while we only need one pre-set and
one acquision for the first position angle P.A.=0. As we could not find an observing
template that changes the instrumental rotation angle only without presetting the
telescope, we repeat the preset and the acquision 4 times, which should be unnecessary
and can be skipped in the actual operation. This is why the total execution time
(1.42h) exceeds the awarded time (1.2h), however, if we subtract the unnecessary
telescope preset/offset, the total execution time is 1.1h. We have contacted paranal
observatory staff (paranal@eso.org) and also the instrument scientist of SINFONI,
and still waiting for their reply. Because of the urgency of the observation, we
will submit the OBs as they are now. In order to reduce the telescope preset
and the minimize the acquision time, and also the time critical nature (and possible
simultaneous observation with CRIRES. see below), we would like these OBS done back-to-back.
The visible magnitude of the star is expected V=10-12.
We have CRIRES runs 281.C-5031(D), 281.C-5031(E), and 281.C-5031(F). We appreciate
if the SINFONI runs are executed as close as the CRIRES observations, but if this
makes too much
tight constraints, we prefer the observation to be done without coordination. If
the observations are done in the same nights, that would be already great. a few
hours of mismatch is acceptable, and greatly appreciated.

Critical Observing Condition Constraints
Time-Critical Aspects
The one of the goals of the observation is to monitor the spatial variation
of the line emission with various probes like Fe, Si, and H2 in order to capture
the very early phase of a birth of a jet. We have three runs, A, B, and C, and requested
that the runs are distributed so that the interval of the each run is at least 2
days. We hope that the all three runs will be done within 2 weeks (the interval
of the first run to the last fun), but a few days of longer interval is no problem.

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?
