Fig. 7

Observability of Group Ia,Ib (left) and Group IIa (right) models with SOFIA HIRMES. Coloured disc models are detectable (≥5σ) with a 10 h integration. Dark red dashed line shows the SPICA/SAFARI 1 h detection limit. The Origins Space Telescope 1 h detection limit (~1 × 10−20 W m−2) lies below the limits of the figure. The fluxes are calculated for a distance of 150 pc.
