Seems we will need to settle this is to run a sim with simopt.rndeps turned
on...

Well, just looking at reduc_makesim, can't we pretty much guarantee that a TnoPol sim will have all zero Q and U maps?

1021 q.gamma=(1-q.epsilon)./(1+q.epsilon);
1328 sky=cmap.T + q.gamma(k)*(cmap.Q.*cos(2*alpha*pi/180) + ...
                               cmap.U.*sin(2*alpha*pi/180));

(The latter is 'linear' interpolation, which is the original function of gen_sig.) There is just no way to turn epsilon<1 into T->P leakage in reduc_makesim!

Is that right? Isn't T the average level and half the amplitude of the
variation is Q?

Seems we will need to settle this is to run a sim with simopt.rndeps turned
on...
