Variations
These are interesting variations related to the CDC:
- CDC_8mm_0T, CDC_9mm_0T, CDC_10mm_0T - versions of time-distance tables for different sized straws, no magnetic field. only 25 tables generated, with mixtures of 47/53 to 53/47 of Ar/CO2, in 0.25% increments.
Tables
CDC/timing_offsets
1-3522 | timing offset, t0 (ns) |
CDC/wire_gains
1-3522 | gain correction factor |
CDC/wire_alignment (3522 rows)
dxu | upstream wire end displacement - X |
dyu | upstream wire end displacement - Y |
dxd | downstream wire end displacement - X |
