Information on resource 'Wavelength Calibration Tool'

The Wavelength Calibration Tool converts pixel coordinates of a one- dimensional calibration-lamp spectrum into a physical wavelength scale. Calibration requires a corresponding reference lamp spectrum with an already known wavelength axis, supplied by the user or selected from the built-in reference data. The service uses Dynamic Time Warping (DTW) to match emission peaks and RANSAC to reject incorrect matches and construct a robust polynomial dispersion solution. Users can inspect diagnostic plots and residual errors, then export the calibrated spectrum and calibration solution.
