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 |
dyd | downstream wire end displacement - Y |
CDC/alignment
CDC_ALIGN_UPSTREAM_DZ | upstream endplate z displacement |
CDC_ALIGN_DOWNSTREAM_DZ | downstream endplate z displacement |
CDC_SAG_RADIUS |
CDC/cdc_gas_tables, 41 rows
1-100 | time-to-distance lookup tables |
CDC/drift_parms
CDC_DRIFT_FUNCTION | index for which row of CDC/cdc_gas_drift should be used |
Note - maybe this should be a JANA parameter?
CDC/MC/drift\_func\_parms
CDC_DRIFT_A | Transverse drift function parameters |
CDC_DRIFT_B | |
CDC_DRIFT_C | |
CDC_DRIFT_D | |
CDC_DRIFT_A_L | Longitudinal drift function parameters |
CDC_DRIFT_B_L | |
CDC_DRIFT_C_L | |
CDC_DRIFT_D_L |
CDC/fit\_parms
CDC_VARIANCE_A | Kalman filter parameters |
CDC_VARIANCE_B | |
CDC_VARIANCE_C |
Deprecated
The following tables should not be used anymore:
- CDC/cdc_drift - parameterized time-to-distance function
