spectrally weighted exposure maps

Hello all,
 I am producing spectrally weighted exposure maps in several different
energy bands, for the purose of creating exposure map weighted images
in those bands, and then summing these images. Is it correct to compute
the spectral weightings in each of these bands seperately with spectrum.sl,
so the weightings add up to 1 in each band, or should one compute the
weightings across the whole energy range, and then use the ones relavant
to a particular energy band, when making the exposure map for that band?

 Cheers,
 Ben Maughan
