Number of stars in the TESS input catalog for which BH companions with given masses and periods are searchable with self-lensing (left panel) and phase-curve modulations (right panel). Here, we count the effective numbers of stars, considering the fraction of systems with suitable orbital inclinations assuming that the orbits are isotropic. Here, the companion mass is extended down to ﹩1{M}_{\odot }﹩ to check the searchability of NSs as well.
