   Solar spectral distribution,
   from \citetads{1976asqu.book.....A}. % Allen AQ 3rd
   $F_\lambda$ = astrophysical flux at the solar surface with
     spectral irregularities smoothed;
   $F'_\lambda$ = astrophysical flux at the solar surface for the
     continuum between lines;
   $I_\lambda$ = radially emergent intensity at the solar surface with
     spectral irregularities smoothed;
   $I'_\lambda$ = radially emergent intensity at the solar surface 
     for the continuum between lines.
   ``Astrophysical'' flux $F_\lambda$ is defined as 
     $\pi \, F_\lambda \equiv {\cal F}_\lambda$ with 
    ${\cal F}_\lambda$ the net outward flow of energy through a stellar
    surface element.  The astrophysical flux is often
    prefered because it has $F_\lambda = <\!I_\lambda\!>$
    with $<\!I_\lambda\!>$ the intensity averaged over the
    stellar disk received by a distant observer.
    It has the same dimension as intensity, whereas
    ${\cal F}_\lambda$ is not measured per steradian.
