Hi all,

Returning to the problem which was discussed yesterday with STT reconstruction efficiency with the version of stt reconstruction code used on GRID, below I present plots with multiplicity of reconstructed tracks with version used on GRID and latest stt code from svn.

Just to remind it's decay eta_c->phi phi-> K+K-K+K-, i.e. in ideal case 4 charged tracks are expected.

On GRID:
index.php?t=getfile&id=6449&private=0

From SVN:
index.php?t=getfile&id=6450&private=0

I.e. problem with drop in reconstruction efficiency is resolved.

Dima
