VLBI Polarimetry Study of the CJF Sample

	This summer I worked with Greg Taylor and Bob Zavala studying
5 GHz VLBI polarimetry data of 182 sources from the Caltech-Jodrell
Bank Flat-spectrum survey.  Because our sample ranged in morphologies
and optical classifications, we grouped these flat-spectrum,
extragalactic sources and did a statistical comparison of their source
properties.  We specifically focused on comparing such properties as
fractional polarizations of cores and jets, and the correlation
between jet axis angle and electric vector position angle in the cores
and jets.

	When I arrived in Socorro the data had already been
calibrated.  After editing, imaging and self-calibrating in DIFMAP and
imaging in AIPS, I spent a large part of the summer writing programs
in IDL which would measure meaningful source properties.  As more and
more properties were measured, new and interesting questions about
these sources became evident.  I continued to write more programs
while reading journal articles and comparing our data to the
literature.  At the end of the summer I gave a 
powerpoint presentation about our project.

	While we are still interested in as of yet unmeasured source
properties such as the degree of jet bend, the current goal is to
submit a  paper to the Astrophysical Journal by October.  Due to our
insufficient number of BL Lac type objects in the sample, many of our
results will be more speculative rather than concrete.  However, we do
have a large enough number of quasars to add support to the claims
that there exists a correlation between jet axis angle and
polarization angle in the jet.  I plan to continue working on this
study throughout the year and to present our findings at the January
AAS conference.
