B_nu |
                 B_nu(hnu, kt)

         returns the specific intensity emitted by a black surface at
         photon energy HNU and temperature KT.  The units of HNU and KT
         must be the same.  The units of the result are determined by
         the variable B_nu_scale, which must be consistent with the units
         of HNU and KT.  B_nu_scale is the Stefan-Boltzmann constant
         (sigma in sigma*T^4) times 15/pi^5.  By default, B_nu_scale is
         set to 0.05040366 ((jrk/sh)/(cm^2 ster))/keV^4.  (1 jrk/sh =
         10^17 W)
         HNU and KT may be arrays, provided they are conformable.

B_nu_bar |
                 B_nu_bar(hnub, kt)

         returns the specific intensity emitted by a black surface at
         temperature KT in the energy bins whose boundary energies are
         HNUB.  HNUB must be a 1-D array of bin boundary energies; the
         units of KT must match the units of KT.  Both are in keV, by
         default; see B_nu for a discussion of units.
         The result will have dimensions (numberof(HNUB)-1)-by-dimsof(KT).
         The algorithm has an accuracy of 0.2 percent.  The idea is to
         difference an analytic approximation to the integral of B_nu.
