Judy,
Well, assuming the SA tubes do in fact print faster with Pt/Pd than
the BL, as many experienced platinum printers claim, the peak
sensitivity must be somewhere around 414. But the SA tubes ( and I
tested two of them, one by URI and another from Hamilton
Technologies) definitely print slower with all of the processes I
have tested. But I don't do Pl/Pd.
And yes, I talked to Voltarc and received some spectral distribution
curves from them for a number of their aquarium and habitat tubes. I
don't have the one for the AQA, but from from other literature it
appears to be very similar to the SA.
