Looking at fgt inefficiencies

 Data:

HV scan with 50V

starting with

 

/star/data06/FGT/A/data/st_physics_13109033_raw_4010002_1351.MuDst.root

 

What was done:

Straight line fit, min 3 points, pointing to vertex in 20cm.

Look at strips in the vicinity where we would expect a hit. The file lists the chi2 for the track, in general it is  small around 0.1 cm.

What we see:

R clusters seem to be there sometimes but often do not fulfill seed. That should be remidied easily 

Phi clusters seem to be more problematic. Note that there only seem to be phi clusters with positive angle. Probably because I have some modulo 2*pi wrong, or it was really outside the acceptance (but then there shouldn't be an r hit where there is are no phi strips found)

 

Of course there might be more bugs as well.
