The line between 495 nm and 505 nm reads 598, 0.2300.

In the 2012 copy I have, it reads 498, 0.2300, which makes more sense if 
the nm column is intended to be in numerical order.  I also saw an 
appropriately-sized spike in the 500 nm area on a HPS spectral graph I 
found on line.

The spline name is ES_Tungsten_Incandescent3K.  Perhaps the file was 
updated by Ive, and he/she never shared it with you.  I'm guessing that 
I must have downloaded the 2012 version from the SpectralRender page 
(and renamed the 2009 version before unzipping the newer file).
