Hello,

after switching to the new external packages (Feb11) Cherenkov photons in the Barrel DIRC simulation started to die on the mirror (see pictures - first is with the old Jan10 packages, the second - with the new Feb11 ones).

I used exactly the same code (PndDrc class and simulation macro) to produce these two pictures, only the version of external packages was different (Jan10 and Feb11).

And I also checked the geometry - it has no overlaps.

I would appreciate any hint helping to find out where does it come from.

Best regards,
Maria Patsyuk
