But… are we ready for a common mDST?(common = all detectors in + all groups could use)
Well, yes, as long as we are not too dogmatic…
Big Four: settled on contents & quality cuts for TPC info ? ~ high compression
newer systems still developing cuts/analyses ? would prefer less compression
- EMC
- depending on analysis (pp or AA), need hits, clusters, tower sums
- keeping all (redundant info) means data expansion ~x2 relative raw data
- ~15KB/evt central AuAu (raw data ~8KB/evt)
- on-the-fly expansion ~ 1 sec/evt
- RICH and TOFp
- compression could be quite high eventually, but for now…
- each would desire ~ 1KB/evt (central AuAu)
- FTPC
- assume similar information volume/track as main TPC
