Spectrometer

Which built-in geometry is used. Custom uses the exact values from the geometry dialog.

Smart Manual Custom

Smart chooses preset A or B automatically from the detected detector crop.

Denoising

How background noise is removed before tracing.

U-Net Morphological opening

U-Net is the default neural denoiser. Morphological opening is classical and needs no model weights.

Geometry fit

The shared fit over all traces. Off holds that term at zero.

Fit perspective & tilt (γ, δ)When off, γ and δ stay at zero (same as CLI --no-tilt-fit). Fit radial distortion (k₁, k₂)When off, lens-style radial terms stay at zero. Pin parabola vertex to brightest spotThe shared vertex stays at the detected bright pixel; rotation and tilts still optimise.

Ion species

Each element adds all charge states from 1+ through its atomic number Z to the classification ladder.

Force analytical hydrogen referenceWhen off, phosphor and Cu runs prefer the detected H trace; standard runs use analytical H unless H is labelled manually.

Label m/q merge tolerance

Species whose m/q is within this band of the closest match share one label (0% = closest species only). Independent of the ±18% classification match tolerance.
