NASA space telescope  SPHEREx
Sensitivity of SPHEREx and current surveys (all at 5σ). The SPHEREx sensitivity is quoted in each spectral channel at current best estimate (CBE, top) and maximum expected value (MEV, bottom) performance. The sensitivity does not include the effects of astrophysical source confusion, which is significant at the deep survey depths.
