% This is a cut down version fo the
% Finesse model for the full dual recycled inteferometer, with Fabry-Perot
% arm cavities and OMC.
%
% This tests 2 ROM files. Each has a 1nrad in xbeta and -0.5nrad in ybeta
% on both ITM and ETM, there is also a square aperture included.
%
% The ROM code has been checked to ensure that the respective tilts and
% square aperture give the same answer as that when you use Bayer-Helms
% xbeta/ybeta and the analytic solution to the square aperture coupling.
