General Description

• We aim to measure the geometry of the circumstellar material around a
   sample of 11 T Tauri and Herbig Ae/Be stars.
  Using AMBER's HR-K (for MWC297) and MR-K (for the 9 target stars) and FINITO fringe
   tracking, we want to measure the visibility both in the K-band continuum as well
   as in the Brackett-Gamma 2.1661 micron emission line.
  
  As DIT, we have specified the recommended value of 0.5s (for MR-K) and 3s (for HR-K).
    If necessary, please adjust this value to the given atmospheric conditions and
   to the FINITO performance (using the same DIT for the calibrator and science OB).
  
  
  *** PLEASE NOTE FOR SCI_HD144432:
  HD144432 has a faint companion at a separation of 1.4" (PA=4 deg; Delta-V approx.
   4.5 mag; Delta-K=3.1 mag; see Carmona et al. 2007, A&A 464, 687).  Please center
   the AMBER fiber on the brighter/southern component (see also attached high-resolution
   finding chart).
  
  *** PLEASE NOTE FOR SCI_MWC863:
  MWC863 has a companion at a separation of 1.1" (PA=236 deg; Delta-V approx. 3.4
   mag; Delta-K=2.4 mag; see Carmona et al. 2007, A&A 464, 687).  Please center
   the AMBER fiber on the brighter/north-eastern component (see also attached high-resolution
   finding chart).
  
  *** PLEASE NOTE FOR SCI_SCrA:
  SCrA has a companion at a separation of 1.4" (PA=157 deg; Delta-V approx. 1.0 mag;
   Delta-K=0.7 mag; see Carmona et al. 2007, A&A 464, 687).  Please center the
   AMBER fiber on the brighter/north-western component (see also attached high-resolution
   finding chart).
  
  The calibrators and their characteristics are (UD diameters from ASPRO):
  
  HD 98560,  F6IV,  UD diameter=0.478 +/- 0.033 mas

  HD 145921, K2III, UD diameter=0.943 +/- 0.065 mas
  HD 153363, F3V,   UD diameter=0.478 +/- 0.033 mas
  HD 166460, K2III, UD diameter=1.577 +/- 0.109 mas
  HD 177565, G8V,   UD diameter=0.563 +/- 0.039 mas
  HD 179758, G5,    UD diameter=0.426 +/- 0.029 mas
  HD 187660, K5III, UD diameter=1.865 +/- 0.129 mas
  HD 193799, G9III, UD diameter=0.448 +/- 0.031 mas
