     follow up to the CLASS gravitational lens survey
     (S.T. Myers et al., 1995, ApJL, 447, L5).

<P>Here are some more data and scripts, intended for more experienced
CASA users and exploring more technical uses of the package.   These

likely need to read through them carefully and in some cases
cut-and-paste commands to their casapy session.
