| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Workspace | InOut | MatrixWorkspace | Mandatory | Workspace whose instrument parameters are to be cleared. |
| LocationParameters | Input | boolean | True | Clear the location parameters used to calibrate the instrument. |
This algorithm clears all the parameters associated with a workspace’s instrument.
Parameters are used by Mantid to tweak an instrument’s values without having to change the instrument definition file itself.
The LocationParameters property specifies whether or not to clear any calibration parameters used to adjust the location of any components. Specifically, it will clear the “x”, “y”, “z”, “r-position”, “t-position”, “p-position”, “rotx”, “roty”, and “rotz” parameters.
