Skim ratios for skims to be run by PASS1 are given below. Not all skims are ready and these are left blank. Also the SVERTI skim is not prescaled by 10% yet, this will probably be done at the actual skim stage. More modes will be added to the SEZDEE skim, like modes with photons, pi0s, etas, omega0, etc. PASS1 will just sets skimbits at the moment.
The next table compares the skim ratios for file 2 of run 10910 using DVINIT_OLD, new DVINITNEW with Target Silicon information, and new DVINITNEW without the Target Silicon information. All numbers were obtained on fdei01 (ALPHA/OSF1) except as indicated. There were 38172 output events for this file and for the SGI run with new DVINITNEW with Target Silicon information, I have listed in () the number of extra (+) or fewer (-) events compared to OSF1.
