It isn't limited to papers with OBAs.

I first thought of a spectral response of an inkjet coating component at 
that range, whether caused by a specific component or a fluorsecence 
effect. But sometimes another measurement of the same paper gives a 
smoother curve. I really think it is the short interval of 5Nm, a small 
peak  in the Xenon light near 530Nm and the curve fitting not coping 
with that to produce a smooth curve. It is one of the things I want to 
correct, redo some measurements and on the other hand dampen the hickups 
in the curves. I find it more important to get  more data that can be 
compared than getting that range in order.
