Here is a description of RISE:
in kumac file one has to specify:
setenv RICH_CONFIGDIR $HB/$HBVERS/geo/rich
and in usevnt.F (after dgevnt()) one has to call:
rcrings();
The program will initialize itself during the first call and no other
initialization is necessary.
- The reconstructed information is stored in RSEG table:
- r.xf = reconstruction space, horizontal angle
- r.yf = reconstruction space, vertical angle
- r.time= Cherenkov angle
- r.dtim= beta (=v/c) of particle
- r.txf = tx of particle
- r.tyf = ty of particle
- r.chi = chi2 of particle
- r.cvf = covariance matrix on tx,ty,Cherenkov angle (instead of Q/p),
other elements (x,y) set to zero.
- r.fit = MTRA number of reconstructed particle
The note on ring reconstruction idea is
HERA-B 98-088
