Extended Data Table 2 Detectability of surface mineralogy with MIRI/LRS

From: Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3

  1. Number of secondary eclipse observations needed with MIRI/LRS to characterize the surface of SPECULOOS-3 b. The distinguishability of models was not analysed beyond 30 eclipses. Ten eclipse observations should allow to distinguish 50% of competing surface models with 4 σ confidence (and 70% at 2 σ).
