Catch Up

So I haven't posted in a while due to e7even's ineptness, grrr. Things are looking better now connection wise anyway.
Been looking in more depth about how the two versions decide if a track is attached to the IP or not, by looking at how the fraction of lone IP's varys with the impact parameter of the track input. We get the plot shown where the C++ (green) has a sharp cut at exactly sqrt(1000) microns!! And the fortran has the slow rise (blue) Ignore the first and last bins. Oh this is for spherical IP of 5 micron, a non spherical IP just smeers the change a bit more.
On good news have the batch farm doing my bidding again, need some data disk though.
I'm on the trail of some strangness in the covar matrix conversion... stay tuned!
