Extended Data Fig. 3: Comparison of ENIIGMA fit with and without silica.
From: Refractory solid condensation detected in an embedded protoplanetary disk

a, Model with silica (M5(s)) over the 7.75–13.20-μm range. b, Model without silica (M4(s)). Silica improves the fit in a statistically significant way from 8 to 9 μm and at 12.5 μm.
