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.https://dachs.fai.kz/misc/wvl_calib/comp/infoGeneralhttps://vo.fai.kz/calibrationhttps://dachs.fai.kz/misc/wvl_calib/comp/capabilities
