- f250 data (David)
- Looked at R2931, mode 7 data, relatively high current, closest to expected running conditions
- BCAL produces about 0.4 kB/event, FCAL about 0.5 kB/event, FDC about 0.6 kB/event. However most of the data is in form of headers, not content.
- Presently the BCAL content represents less than 20% of the BCAL data volume and about 1.5% of the overall file size..... (Why is the overhead so high?)
