光度

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1 stellar radiation may be represented by some black body equivalent and 2 within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.
