This directory 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.  When calculating W at a single wavelength, enter it as
lambda1 & just input anything for lambda2.
