Spot information

Spot information

  • Find spots: Automatic spot detection with advanced peak-finding using local maxima and background subtraction.
  • Donut filter: Applies a donut-shaped (annular) filter to enhance ring-shaped diffraction features and suppress the central beam.
  • Delete spot / Clear spots: Remove individual or all detected spots.
  • Reset range for all spots: Reset the fitting range for all spots to default.
  • Copy to clipboard: Copy spot positions and intensities to the clipboard for external analysis.

Index

Index

  • Crystal selection: Choose which crystals from the crystal list to use as candidates for indexing.
  • Search: Run the indexing algorithm to find the best-matching crystal and zone axis.
  • Tolerance: Set the acceptable deviation in d-spacing and angle for a match.
  • Results: The best matches are displayed with crystal name, zone axis [uvw], and individual spot indices (hkl).
