A pdf of the drawing of the crdc masks can be viewed here
NOTE-> The GValue "names" that we are using (currently) for mask calibrations are called
- CRDC1_Y_SLOPE
- CRDC1_Y_OFFSET
The slope and offset the CRDC_X values are always the same:
- CRDC#_X_SLOPE = 2.54
- CRDC#_X_OFFSET = -281.94
To get the Y values you must use the known values from the map pdf above and correlate them to the values you see in your map run file.
Notable points on the map pdf:
| Hole Number | Local Position | Centered Position |
|---|---|---|
| 29 | (12.3015,8.886) | (0,0) |
| 61 | (12.3015,7.9018) | (0,0) |

If you need more points for your fit you can determine the conversion between coordinate systems given the above table and us the map pdf to get the relevant values.
