Found out that if one will set ignored_portion in touschek_scatter less than 1e-5 (1e-6, for example), all simulated particles will be put to tracking, as if ignored_portion were 0.

Re: Impossible to set ignored_portion less than 1e-5 in touschek_scatter function
Mikhail,
I see in the code that values less than or equal to 1e-6 are treated as zero. I think the assumption was that for ~1 million particles, the algorithm that ignores particles probably doesn't give very precise results when ignored_portion is so small. However, it shouldn't hurt anything, so I've reduced the cut-over value to 1e-9.
Thanks for reporting the issue.
