Cool starspots systematically distort spectral morphology, affecting temperature and gravity estimations.
Single-temperature models can overestimate temperatures by up to 700 K and underestimate surface gravity by 1–2 dex.
Two-temperature spectral fits consistently outperform traditional methods, especially in the 3350–4000 K range.
Spot corrections lead to increased inferred masses by up to 80% and ages by up to 0.5 dex for stars in the 0.3–0.8 M ⊙ range.
