I AM using a tab with of 4 but when I copy-and-paste into the 
news reader the tabs get expanded to 8. I actually thought, the 
news reader would transmit the \t characters but it looks like it 
is converting them to 8 spaces before sending. 
But no problem, I'll do better the next time. 

BTW, after posting, I wondered myself why I was using 0.5*(EP2->t+EP1->t), 
i.e. the average. We could even do a linear interpolation which should be 
much better: We know the f and the t values!

Since you (Thorsten) are the guy who ported the Suzuki code to povray: 
What do you think?
