SINSZC_D3a15504_NGSAO_P84-# 16.3 K=19.2 17 arcsec H_alpha: line at 2.221um
The main characteristics of the observations are as follows.
- The PA has been carefully chosen for all targets, primarily for scientific reasons
as well as to ensure the tip-tilt reference falls within the Field Selector field
of view (FOV) whenever relevant.
THIS PA SHOULD NOT BE MODIFIED.
- The Telescope Guide Star has been selected for all targets ("SETUPFILE" and
coordinates specified explicitely), to allow for accurate registration of
different OBs of a given target.
THE TGS SHOULD NOT BE MODIFIED (THE SAME TGS IS NEEDED FOR ALL OBS OF A GIVEN
SOURCE).
- At this time, the OBs of only 1 target are submitted (see section on
Waiver Requests).
- OBs are named after the targets, with "-0", "-1", "-2", etc. appended for
different OBs.
- While there is no real priority among the OBs of the target, we would however
prefer, if possible, that the OBs are observed starting from "-0" and in increasing
number, as given in the OB name.
- The DITs for our exposures of our faint targets are 600s.
- The brightest spectral feature of the targets is H_alpha in emission;
the observed wavelength of the line is given in the table above.
- We are using the 100mas scale, with FOV of 3.2"x3.2", and the following strategy.
The target can be observed with an on-source dithering pattern, where two
successive exposures are offset roughly along E-W by about 1/2 of the 3.2"x3.2"
FOV (i.e., about 1.5") for pairwise sky subtraction. Small jitters are done
around the two main dither positions to minimize the number of redundant
positions.
Remarks on the finding charts:
- Two finding charts are provided for each target and OB, following the instructions
for SINFONI.
(1) The first one (SINSZC_{source_mode}_fchart1.jpg) has wider FOV; a large and
a small black square show regions 1' x 1' and 8" x 8" centered on the target;
the TTS is labeled "R1". The larger dashed rectangle shows the Strap Field
Selector FOV of the AO system.
(2) The second one (SINSZC_{source_mode}_fchart2.jpg) is zoomed in on the target,
with the large and small solid-line squares showing regions of 8" x 8" and
3.2" x 3.2" centered on the target. In addition, two dashed-line squares
show the outline of the two main dithering positions.
- In addition, a third finding chart is included,
(SINSZC_{source_mode}_fchart3.jpg). It is similar to the zoomed
SINSZC_*_fchart2.jpg but based on higher resolution VLT/NACO imaging.
Waiver Requests
Two Waiver Requests were submitted:
183.A-0781G.01.WAV: Request for delayed submission of part of the OBs.
Submitted on Aug 2, 2009; Granted on Aug. 5, 2009.
183.A-0781G.02.WAV: Request for an increase of the OB execution time limit to 1h30.
Submitted on Aug 2, 2009; Granted on Aug. 5, 2009
Critical Observing Condition Constraints
Transparency constraints:
- For all OBs, CLEAR sky transparency conditions is acceptable, as specified
in the proposal.
Moon constraints:
- Conforming to our proposal, there is no constraint on lunar phase and so
the illumination is set to 1.0.
- For the submitted OBs, the TTS is faint (R ~ 16), however, so we have set
the constraint for moon distance to 50 degrees
(following recommendations from the ESO SINFONI P2PP Web pages, through
http://www.eso.org/sci/observing/phase2/ConstraintsSet.html#InsSpec).
Seeing constraints:
- Seeing < 0.8", as specified in the proposal.

Is this a Pre-imaging run ?
Pre-imaging Requirements
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?
