It takes about 3 months after taking the data for them to derive the constants. Reconstruction is done on Apollo DN10000 workstations connected to their IBM 3090 by a channel-VME interface. The recon output is streamed three ways RECON: DST:miniDST at 200:20:3 kB/evt.
Data quality monitoring is handled by a single person at a time during the run. The feedback from reconstruction takes about 2 days to get back to the experiment.
About 1/2 of the group uses PAW for analysis. The COMIS facility is thought to be slow and too buggy to depend on for final analyses, which are performed with compiled code.
They do not have a very good handle on how they use their disk space (cf D0 in our FNAL trip report).
He suggested we try using a plot of phi vs theta for looking at CRID data. A ring from the liquid would appear as a vertical line.
They are looking into shareables for UNIX plus dynamic loading. This is intended for people, once they are happy with their COMIS macro file, to compile them, link them in interactively and run the faster, compiled code on their ntuples. This is being developed for HP so far.
Tony Osborne wanted to make it clear to us that CERN CN is not an infinite source of manpower and, that if we wanted features, etc from them, we would be expected to contribute by collaborating on projects.
