Comparison of the magnitude range and size of recent, ongoing (colored bars), and future (gray bars) stellar spectroscopic surveys with those of the MWBP, which is among the largest stellar spectroscopic surveys currently underway or planned. The MWBP complements the MWS in extending to brighter stars. Both surveys measure spectra for stars fainter than the Gaia Radial Velocity Spectrometer limit and are each likely to include ∼10 million stellar spectra when complete. See text for details.
