Description
-----------
 
    This bank contains coefficients which define the angular distribution of
light emitted by the laserball calibration source.

For backward compatibility, the laserball zenith and azimuthal orientation and
the laplace series coefficients are given first, though these are no longer used.

The current implementation of the angular distribution of light emitted by
the laserball uses the coefficients for a 6th order polynomial giving the mask
function in theta and an emission probability grid in
12 (costheta) * 36 (phi) bins.  These coefficients follow, in six wavelength
bins.
