Expand description

Compute Doppler-broadened cross-sections from precomputed unbroadened cross-sections.

Returns Doppler-only cross-sections. Resolution broadening is NOT applied (issue #442: must be applied after Beer-Lambert on total T).

Like broadened_cross_sections but skips the expensive Reich-Moore calculation (step 1). Use unbroadened_cross_sections to compute base_xs once, then call this function repeatedly with different temperatures.
