Contains the equations and constants to calculate the emittance from a blackbody, i.e., evaluating Planck's equation. The program stored in BBOD allows integration of W (emittance, in either watts or photons per second per square centimeter) over a wavelength band or at a single wavelength. dW/dT can also be integrated. The routine stored in PLOT plots both the watts and the photons/sec curves on the same frame. |
