Quick Reference

The brightness of a star at a single wavelength. Such magnitudes are important in assessing the variations in magnitude to be expected when a given star is observed through different filters. The monochromatic magnitude is a mathematical ideal that cannot be measured in practice, but can be approximated by narrow-band photometry, provided there are no strong spectral features in the band.
