In October, I added code to AMOEBA to fit spectroscopic and photometric data.
Work on implementing the hierarchical model format was continued, and I was 
able to reproduce radial velocity data of Algol, a triple system. I also
simulated visibility data for Algol and mapped it with AIPS as a demonstration.
For this purpose, I added R. Wilson's (Univ. of Florida) code to compute light 
curves and images of interacting binaries to AMOEBA. I fitted a new orbit of 
Mizar A to combined Mark 3 and NPOI data with AMOEBA.

I was on vacation from October 28 to November 13.

In the second half of November, I finished the revisions of my paper "The radio 
jet of 0153+744", and submitted again to Astronomy & Astrophysics. The proposal
to observe this quasar with the VLBA arrived a day late at NRAO and will there-
fore be considered for the next deadline in February. I installed another
software package for the reduction of VLBI data, the Caltech package.

Some work was done on CHAMELEON, such as adding triple amplitude calibration,
color hard copy plots, and on-line help. Data was obtained with NPOI on the
binary Beta Aurigae, but the squared visibility amplitudes suffered from bad
detector statistics and maps were therefore of poor quality. It was discovered
that the triple amplitudes on the other hand are unbiased and a first 
successful test of the "phase bootstrapping" technique was accomplished, i.e.
fringes were tracked on the two short baselines of the array, while the long 
baseline on the specific star chosen (Alpha Arietis) measured very weak fringe 
contrast outside the first null of the visibility function. An observing 
program was put together containing a list of the most promising stars and 
binaries for presentation at the IAU 189. Several nights of data were reduced
and models of limb-darkened and uniform stellar disks fitted.

Work on a paper about the Mizar A images, to be submitted to the Astronomical
Journal, was begun with K. Johnston and the second draft was handed over to 
T. Armstrong for editing the final version.

In January of 1997, I plan to attend the IAU Symposium No. 189 on "Fundamental
stellar properties: the interaction of observation and theory", to be held in
Sydney, Australia. I plan to present a poster on "Imaging and modeling of 
spectroscopic binaries by long baseline optical interferometry". I completed
the poster by the end of the quarter.
