General Description
Deep (4 hrs + overh) spectroscopic observations of a faint (K~20.6) galaxy
with coordinates (J2000) 22:32:49.25 -60:32:11.7. The instrument setup is: SPAXEL
size 0.25 arcsec (8"x8" f.o.v.), K-band. The galaxy has a size of about 1.5 arcsec.
No other sources are expected to fall in the Sinfoni f.o.v. in these observations.
Each OB is composed by two templates: the acquisition template Sinfoni_ifs_acq_noAO
and the science template Sinfoni_ifs_obs_GenericOffset.
The acquisition template will point a brighter (K~16.5) reference star located at
22:32:47.44 -60:31:59.9 (J2000), i.e. at a distance (arcsec) delta(RA)=13.6 and
delta(Dec)=-11.8. After having pointed the reference star the acq. template will
move the telescope to the faint galaxy through a blind offset of RA=11.6" and Dec=-9.8".
Thus, when the acquisition template is completed the faint galaxy is in the southern-eastern
corner (position A) of the f.o.v.
The science template executes the first DIT=300s exposure at the position A (offset
0" 0"). Then, it moves to position B at the opposite corner with an offset 4" -4"
and execute the 2nd exposure and so on. The faint galaxy will be observed following
a dither pattern composed by 8 offset positions (ABBAABBA) with DIT=300s each.
It is possible that the 6 OBs are carried out in different nights. To obtain a precise
coaddition of the OBs the USD advised us to use the same guide star for all the
OBs.
For this reason, in the acquisition template, we give the coordinates [22:32:43.385;
-60:28:35.76] of the guide star GSC0911800974 having a magnitude m=12.6 selected
from the Guide Star Catalog at ESO at a distance <8' from our faint target galaxy.

Source(s) of Pre-imaging
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?
