  The main characteristics of the observations are as follows.
  
  - The targets have no particular priority: they are all required
    as pre-imaging for a subsequent run 081.A-0672(B).
  - For this pre-imaging run, there is one OB per target.  OBs are named after
    the targets and with "-0" appended.
  - 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 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 081.A-0672(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 (about 4 arcsec), 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:
  
  081.A-0672A.01.WAV: for an increase of the OB execution time limit to 1h30.
                      (submitted on 11 February 2008, approved on 11 February 2008)
  
  A Target Change Request was also submitted, and accepted on 13 February 2008

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.
