New source model

Stored values feed the TG-43 perpendicular-axis calculator. Look up published parameters in the AAPM TG-43U1 report or vendor / consortium datasheet for the source model in question.

Radial dose function gL(r) — polynomial

gL(r) = a0 + a1·r + a2·r² + a3·r³ + a4·r⁴ (r in cm). Defaults to a constant 1.0; replace with the polynomial fit published for your source model.
