General Description

• This program aim for high resolution imaging of nearby transitional disks
   with large inner holes. It
  contains both NACO Ks-band coronography with the 0.7arcsec semitransparent mask
   (except for HR4796 and
  HD 135344 for which we can use the opaque C_0.7 mask) and Narrow-band imaging with
   the NB_2.12 and NB_1.75 filters and the S13 camera.
  
  The aim of the coronographic and narrow-band filter observations is quite challenging
   but it could be 
  very scientifically rewarding if well done because we may be able to image for the
   first time with 
  NACO the detailed structure of the disk inner rim in these transitional disks where
   it is believed 
  that planets may be forming. In order to raise the probability of these OBs being
   executed, I have
  reduced the observing constraints from those in the proposal to values of seeing
   and airmass where 
  the AO still is effectively working.
  
  The observations were optimized with the NAOS PS for using the VIS WFS and all stars
   are bright enough 
  (V = 5.7 - 13.8) to be used as natural guide stars, which increases substantially
   the Strehl ratio.
  All V, and K magnitudes of the stars and their associated reference PSF stars are
   given in the
  comments field of the OBs and in the finding charts.
  
  Every coronographic or imaging OB has a corresponding PSF_ OB, which should be executed
   just after or
  before the science OB to keep the paralactic angle small and allow a good PSF subtraction
   (details in the 
  comments field of each OB).  I have included a NACO_coro_cal_Night_Calib at the
   end of each coronographic 
  OB.
  
  I have used the finding charts for the coronographic acquisition for the imaging
   OBs, since the
  field of view is the same and the filter very similar.

Waiver Requests

• Three waiver requests were submitted and approved:
  
  Waiver 1: On 05/02/2007 the modification of target SR21 for DoAr21 is accepted by
   ESO.
  
  Waiver 2: On 09/02/2007 the coronographic observations, wich were part of the proposal
   but not 
  specifically described in the Intrument Configuration box, were approved.
  
  Waiver 2: On 01/03/2007 the narrow band filter imaging with filter NB_2.12 were
   approved. These 
  observations may resolve the fluorescence H2 line at 2.12 and help attaining the
   program objectives.
