VDHMATCH : Counting of matching VDET hits for a given track

The routine VDHMATCH must be called only AFTER a call to JULMATCH. See the note of D.Brown ALEPH 94-135 (PHYSIC 94-118) for more details.

This routine cannot be called when running on a MINI, since it needs the detailed VDET hits which are not stored on the MINIs.

IALTRK

Input argument : Alpha index of a reconstructed charged track (between KFCHT and KLCHT)

IMCTRU

Input argument : Alpha index of the matching ``truth" track as given by JULMATCH (must not be 0)

NTRUE

Number of true VDET hits on this track

NWRONG

Number of true hits on the reconstructed track which truly came from a track other than IMCTRK (split z/r$\phi$)

NMISS

Number of true VDET hits not used in reconstruction (split z/r$\phi$)

NDOUBLE

Number of true hits on the reconstructed track which are associated with 2 or more true Monte Carlo tracks (split z/r$\phi$)
