Does anyone know the spectral sensitivity of a #99 (12) orange filter?

Dan,

I don't have the spectral curves in the Infrared FAQ, 
http://www.infraredfaq.org/  however there is an interesting article 
contributed by Michel Wurtz linked in Section 12 of the FAQ "Infrared 
Filters". The article shows the effects of #12 filters and others on 
EIR.

Hope this is useful, if not to yourself then maybe to others who have 
been discussing EIR recently.
