NASA space telescope  SPHEREx 
The scientifically required point source sensitivity has large margin over the estimated instrument performance. We show above the science requirement (black dashed line) and the MEV (solid colored curve) and CBE (dashed colored curve) performance. Note the Bands 5 and 6 sensitivities is shown rebinned to R=40 spectral resolving power. Bands 5 and 5 easily meet the 9 AB mag (100σ) required for the Ices Investigation.
