General Description

• 1) OBs named NGC3603-01 through NGC3603-15 (called "standard OBs")
  
  The observing sequence is as follows:
  
  Acquisition of AO-NGS (star C) in K, adjust diaphragm interactively to 1", close
   AO loop.
  - observe C in K, offset to A1, observe A1 in K
  - change grating to H
  - observe C in H, offset to A1, observe A1 in H
  
  NOTE: The P2PP checker yields an offset warning, but we indeed do offset to a star.
  
  EDIT: The offsets have now the same signs in both K and H band.
  
  
  Immediately following the Science OB, a Calibration Block with a telluric standard
   is executed (named/numbered accordingly). SINFONI is still set-up in H so that acquisition
   of telluric standard stars is done in H. Note that the telluric can be observed
   under poorer conditions (0.8") than the Science OB because it is well isolated.
  
  Acquisition of telluric standard star HD 98133 (AO-NGS) in H. Strehl ratio is not
   so critical here as long the star does not saturate.
  - observe HD98133 in H (an AB sequence is specified)
  - change grating to K
  - observe HD98133 in K (AB)
  
  Note that of the 15 "standard OBs", 8 have a lowest priority (10; this does also
   apply to their related Calibration blocks). Their status will be reviewd later on
   in P80 (see Waiver Request for information).
  
  
  
  2) OB named "NGC3603-DeepField"
  
  Acquisition and calibration exactly as above, but this time, a deep exposure is
   taken in K and H band in "wide mode" (250mas plate scale). To apply some "jittering",
   a 5-pointing offset sequence has been specified for both passbands (the first offset
   is to the target field, the following four are for the jitter). Immediately after
   the Science OB, please execute "CAL telluric DeepField", this Calibration block
   is as the ones described above, i.e. with 25mas(!) plate scale.
  
  NOTE: Separate sky frames are never taken. This is on purpose.
  
  
  3) Finding charts
  
  NGC3603: For clarity, finding charts were made from ISAAC-K (30"x30" without AO)
   and red WFPC2 (30"x30" and 8"x8") images, since available 2MASS-K images in 60"x60"
   would eseentially just show a blob.
  
  HD98133: No FCs have been included because HD98133 is the brightest (as a matter
   of fact, only bright) star in a 60"X60" field.

Waiver Requests

• Waiver Requets have been granted regading the following issues:
  
  
  1) Tightening the seeing constraints to 0.6".
  
  Permission has been granted in an e-mail by Dr Francesca Primas (Monday, 30 July
   2007). In exchange for this permission, half of the time is demoted in user-priority.
   From the 16 visits, only 8 have priority 1 (highest), namely the DeepField OB and
   7 "standard" OBs, while the remaining half has been issued priority 10 (lowest).
  
  
  2) Adjustment of the AO diaphragm
  
  Because of the brightness of the two nearby stars NGC3603-A1 and B, the AO-loop
   might run in troubles when trying to close on star C. Therefore, permission was
   granted to interactively adjust the diaphram during acquisition (mail by Mario van
   den Ancker on Tuesday, 31 July 2007).

Critical Observing Condition Constraints

• Seeing and airmass should enable the diaphragmed AO-loop to close on star
   C.
  
  Note that Calibration blocks can be executed under poorer seeing conditions than
   the actual science observations.

Time-Critical Aspects

• Please do not execute more than one OB per night, since we are sampling
   the motion of two binary systems (P=4d and P=9d).

Special Execution Requirements

• Immediately after each Science OB, please execute the related Calibration
   Block (telluric standard). Since seeing constraints are much softer for this isolated
   star, variable conditions should not be a problem.

Special Calibration Information

• User-specified telluric standard. Note the brightness of the standard
   star, requiring neutral densities for the AO!
