c₁ / c₂ act over the normalised window u = (x − Xmin)/(Xmax − Xmin), so their units are “counts across the full plot”.

Analysis

Peak A

Peak B

—

Classic ratios: I_D/I_G for carbon disorder, I_2D/I_G for layer count. Area ratio is the physically meaningful one when widths differ.

Shortcuts

dbl-click add peak at cursor

drag ■ apex = centre + height

drag ▪ flank = FWHM

← → nudge centre · ↑ ↓ height

Shift + arrows = 10× step

Ctrl+Z / Ctrl+Y undo / redo

click row select · click again = deselect

Esc deselect current curve

Del delete selected curve

F run auto-fit
