Monthly report for June 2000 by Christian A. Hummel:

Hummel submitted a paper on the double star Zeta Orionis to the Astrophysical 
Journal Letters.

Hummel gained new insights into the dispersion correction of NPOI delays
through discussions with J. Benson and D. Mozurkewich, as well as simulations
of fringe frames. As a result of this, Hummel implemented and successfully
tested a new algorithm which was shown to work down to V=5.
