General Description

• The goal of the program is to spatially resolve the wind in the launching
   regions of Herbig AeBe stars on the AU scales, in the Brackett gamma emission line.
   We want to determine the relative geometry between the gas and the dust of a Herbig
   Ae star (MWC275) and of a Herbig Be star (MWC297) (spatial extension and asymetry)
   to determine the origin of the wind depending on stellar properties.
  
  We therefore would like our stars to be observed twice (2 calibrated points) at
   two **different** hour angles.
  Preferably one point at HA<=0 and one point at HA>=0. Therefore, the OBs are
   duplicated for both stars with different LST constraints. 
  That would certainly require the two calibrated points for each star to be taken
   at different moments of the semester.
  
  We would also like the data to be taken before the end of June, if possible, since
   they would still be part of the PI's PhD thesis.
  And if possible too, we would like to get the data as soon as they are taken (eg
   to get a DVD with the data for each individual observation if they are all made
   at different moments).

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• We request clear conditions and 1.0" seeing.

Time-Critical Aspects

• We would like the two calibrated points to be taken at different hour
   angles. Preferably -2
  

Special Execution Requirements

• Remark added on June 29: since there are not many UTs nights left for
   P79, we want to add this information:
  The observations can be made with any baseline triplet but it would be easier with
   the short triplet.
  We would really like to have the data, so, we are even OK with 1-baseline data if
   the fringes are not found on the three baselines simultaneously - rather than nothing.
  
  Thanks in advance.

Special Calibration Information

• I choose my calibrator stars in both ASPRO (same catalogues than CalVin)
   and getCal (MSC), but not directly from CalVin database.
  So, here is the informations concerning the calibrators:
  
  To calibrate MWC297:
  Name: HD164259 
  Coordinates: 18 00 29.0105 -03 41 24.969
  Proper motion (mas/yr): 154.18 / -44.43
  Vmag: 4.6
  Kmag: 3.6
  SpT: F2IV
  UD diameter at K: 0.6+-0.3 mas 
  Source: getCal (MSC)
  
  To calibrate MWC275:
  Name: HD163955
  Coordinates: 17 59 47.5533 -23 48 58.081
  Proper motion (mas/yr): -5.40 / -50.30
  Vmag: 4.7
  Kmag: 4.5
  SpT: B9V
  UD diameter at K: 0.4+-0.3 mas
  Source: ASPRO
