  1. Once the correct scan number is selected, you can also choose different values for Detector and Positioners if the paths are not standard. This can be done either by changing the text fields or by clicking on the corresponding Browse buttons.

  2. Optional: To select a file to be used as dark data, you can check the Dark data checkbox and select a file, scan number and detector as previously (no positioners are needed in this case).
