Estimated Total Execution Time (hours, including overheads)

• 4

General Description

• Our scientific objective is the observation of the inner region of the
   proposed TTauri objects with AMBER in order to study disc formation and disc geometry
   considering the effects of dust grains in the hottest part of circumstellar discs.
   This run consists of 4 OBs, 2 for targets, 2 calibrators.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• It is mandatory to schedule the observations in such a way that the targets
   are not closer than 5 degrees, at least. As the visual brightness for the scientific
   target HBC 639 (V=14.8) is close to the limit at that Coude Guiding is working,
   we recommend to use a larger angular distance 'target-moon' for this target.

Time-Critical Aspects

• No time-critical aspects.

Special Execution Requirements

• The scientific target AS205 is a 1.3''-binary (position angle = 204degrees,
   measured from North to East and seen from the bright component). Only the bright
   component of the binary should be observed as it is defined in the OBs. 
  The scientific target HBC639 is a 2.2''-binary (position angle = 150degrees, measured
   from North to East and seen from the bright component). The bright component should
   be observed.

Special Calibration Information

• The calibrators were chosen because of their proximity to the scientific
   targets. 
  
  Calibrator for AS205A is
  HD143033: V=7.12, K=3.05, spect. type: M0III, separation: 6.1degrees, obtained from
   CalVin-List
  
  Calibrator for HBC 639 is 
  HD143900: V=6.23, K=3.11, spect. type: K2/K3III, separation: 5.1degrees, obtained
   from CalVin-List
  
  Of course, the Paranal Science Operation Team should have the right to exchange
   these suggested calibrators if it is necessary.
