The main characteristics of the observations are as follows.

- The OBs are prioritized following the scientific priority;
  however, they are all required as pre-imaging for a subsequent 
  run 183.A-0781(B).
  The OBs for the two last sources in the table above have same priority
  "10" - which is observed first is not important.
- For this pre-imaging run, there is one OB per target.  OBs are named after
  the targets and with "-0" appended.  For ZC405081, there are two OBs, with
  "-0" and "-1" appended; if possible "-0" should be observed first.
- The DITs for our exposures of our faint targets are 600s.
- The brightest spectral feature of the targets is H_alpha in emission;
  the expected wavelength is given in the table.  There are no previous
  spectroscopic observations in the near-IR so the actual Ha fluxes and
  morphologies are not known.  The purpose of this pre-imaging run
  is to identify the best targets for follow-up in run 183.A-0781(B)
  with AO based on actual Ha brightness and distribution.
- We are using the 250mas scale, with field of view (FOV) of 8"x8".
  We use "on-source" dithering for all targets: they are sufficiently
  small to fit in the overlap region.  Briefly, two successive exposures
  are dithered by roughly 1/2 of the FOV (mostly along E-W), so that the
  unregistered frames can be subtracted pairwise for background subtraction.
  Small jitters about the main dithering positions are used to minimize
  the number of redundant positions.

Remarks on the finding charts:

- Two finding charts are provided for each target/OB, following the instructions
  for SINFONI.
  (1) The first one (SINFONI_{sourcename}_fchart1.jpg) have wider FOV; a large and
      a small black square show regions 1' x 1' and 8" x 8" centered on the target;
      the offset star for acquisition is labeled "R1".
  (2) The second one (SINFONI_{sourcename}_fchart2.jpg) is zoomed in on the target,
      with the solid-line square showing the full 8" x 8" FOV at 250mas scale.
      In addition, two dashed-line squares show the two main dithering positions
 
      of the sequence, where the source lies in opposite quadrants for any two
      successive exposures (explained above).

Waiver Requests

One Waiver Request was submitted:

183.A-0781A.01.WAV: for an increase of the OB execution time limit to 1h30.
                    (submitted on 03 February 2009, approved on 03 February 2009)

Critical Observing Condition Constraints

Transparency constraints:
- For all OBs, CLEAR sky transparency conditions is acceptable, as specified
  in the proposal.

Moon constraints:
- For all targets, conforming to our proposal, there is no constraint on
lunar phase and so the illumination is set to 1.0.

Seeing constraints:
- Seeing < 0.8", as specified in the proposal.
