LoadIsawDetCal dialog.
Table of Contents
Since ISAW already has the capability to calibrate the instrument using single crystal peaks, this algorithm leverages this in mantid. It loads in a detcal file from ISAW and moves all of the detector panels accordingly. The target instruments for this feature are SNAP and TOPAZ.
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | InOut | Workspace | Mandatory | The workspace containing the geometry to be calibrated. |
| Filename | Input | string | Mandatory | The input filename of the ISAW DetCal file (East banks for SNAP) . Allowed extensions: [‘.detcal’] |
| Filename2 | Input | string | The input filename of the second ISAW DetCal file (West banks for SNAP) . Allowed extensions: [‘.detcal’] | |
| TimeOffset | Output | number | Time Offset |
Moves the detectors in an instrument using the origin and 2 vectors of the rotated plane from an ISAW DetCal file.
