KnowraPhotometric systemLinked fromLinked fromThe 8 pages that link to Photometric system, each with the reason it gives.All 8Related 7Narrower topic 1Apparent magnitudeRelated: Magnitude values depend on the bandpass and zero point used for measurement.Interstellar extinctionRelated: Extinction estimates depend on which wavelength bands define the measured colors.Sloan Digital Sky SurveyRelated: SDSS imaging uses its own five-band system to classify objects and select spectroscopic targets.Distance modulusRelated: Apparent and absolute magnitudes must use compatible bands and zero points for their difference to be meaningful.Color indexRelated: Its filters determine which magnitudes form a particular color index.Atmospheric extinctionRelated: Extinction varies with wavelength, so calibration depends on the chosen filters.Bolometric luminosityRelated: Band-dependent measurements require corrections before they represent total stellar power.
