General Description

We want to investigate the geometry of the disk around the Herbig Be star
 HD 98922 using AMBER and MIDI.  The good spectral resolution of AMBER's MR-K mode
 and MIDI's PRISM should allow us to resolve spectral features such as the Bracket-Gamma
 line (at 2.166 micron) and the silicate bands (9.2-11.4 micron).

=== 2007-01-25 (Change in telescope configuration):
First AMBER measurements on HD98922 (which we have obtained in the course of programme
 078.C-0360(A)), have shown that baseline lengths below 90m are recommendable to
 avoid very low visibilities and to obtain sufficient SNR.  Therefore we changed
 the originally selected telescope triplet UT1-UT3-UT4 to UT2-UT3-UT4.
