I've made some modifications to the radiation condition that use an a 
priori specified wavespeed (rather than the adaptive Orlanski condition 
which in my problems tends to introduce more noise than it lets out...), 
and another version with separate (constant) wavespeeds for external and 
internal modes. I'm happy to send my code to anyone who wants it, 
although I haven't yet done the necessary homework to make an "official" 
contribution to the code database...
