Cyanotype Sensitivity Curve?



Hi,
Can anyone point me to a source for the sensitivity curve for cyanotypes? I.e.
exposure time (or something related) vs wavelength.  I'm interested in using a
light source outside the UV range and would like an order-of-magnitude estimate
of the time required.

Thanks a lot,
Travis
