Monthly report for August 1999 by Christian A. Hummel:

Hummel spent spent a week moving to Bldg. 56 and helping to move other
offices too.

Hummel implemented a more direct diameter fitting routine in OYSTER and
used it to obtain diameters of Delta Cephei and its check star for all
data available. Amplitude and phase of the diameter variation found in
Delta Cephei are consistent with T. Norgren's earlier analysis, but not
with M. Germain's. This work is in preparation of detailed discussions
on this subject at the next NPOI quarterly meeting.

Hummel updated the OYSTER stellar diameter database for calibration purposes
with the NPOI results presented in T. Norgren's paper.
