General Description

• The science objects to be observed are post-AGB binaries which are surrounded
   by a dusty oxygen rich disc. This disc houses both hot (this part of the programm)
   and colder (MIDI) dust. We determined the size of the Keplerian discs in the N-band
   already in other proposals and in the MIDI part of this proposal. With AMBER, we
   aim at determining the size of the Keplerian discs in the K-band as well. We will
   locate the hot inner rim, which is likely at near dust sublimation radius for all
   objects. The MIDI+AMBER combination will provide an accurate determination of the
   temperature distribution in the inner disc and provide some essential constraints
   for our 3D dust models. Moreover, a non zero phase closure measurement will provide
   direct evidence of the non-spherical nature of the emission.   
  
  Hereunder, we provide the observations of science and calibrator targets to be performed
   with AMBER on the AT configuration E0-G0-H0. For each science target, two observations
   are requested at the same triangle configuration. It is not necessary to observe
   the same targets at different projected angles. 
  
  The list of science targets with corresponding calibrators is provided below. Note
   that for each science target (and thus also for each calibrator target) TWO observations
   are requested.
