Monthly report for November 1998 by Christian A. Hummel: CAH went to Flagstaff Nov 2 - 5 for a meeting on aips++ as an environment for NPOI data reduction software. CAH added a brief summary on how to reduce data with his software to the information sent to PIs, and he created an HTML tour of his software which was added to the help pages. CAH implemented logarithmic limb darkening coefficients into the NPOI modeling software. A few small bug fixes were done.
