Don't know about the planar transmission (never done it), but I can happily fit capillary data off my system. I have no quibbles about the effectiveness of ray-tracing, but what I'm using currently with our machine (including tube-tails) does a pretty good job. It eventually gets to the stage that sample prep issues (particle statistics, etc) will have greater effects than very slight inadequacies of the profile fit.
