Brightness temperature definition
WebIn astronomy, magnitude is a unitless measure of the brightness of an object in a defined passband, often in the visible or infrared spectrum, but sometimes across all wavelengths. An imprecise but systematic … WebThe amount of light that we would see at a fixed distance, arbitrarily selected as 10 parsecs, is referred to as the absolute brightness. Equivalently, it is called luminosity. Scientifically, absolute brightness or luminosity is typically (but not always!) measured in units of Watts per meter squared and is often referred to as flux.
