Hot magnitude: Represent the celestial body in the whole radiation The magnitude of the total radiation in the band. The symbol is mb, which cannot be measured directly through observation Multicolor photometry The measured magnitude is calculated by theoretical calculation. First, the radiant star magnitude is determined by detectors with the same sensitivity to all wavelengths, and then the radiant star magnitude is corrected by atmospheric extinction and instrument extinction to obtain the hot star magnitude.
