I've followed the white tile thread to find out that each spectro is
factory calibrated to it's own white tile (which is not 255 white) but
there is also a "black" tile embedded in the spectro platform.

We do a calibration to the white tile before readings... what do (or
can) we do with this black tile? Curious minds like mine wish to know.

The black tile is just there to keep curious minds awake at night...:-)

But you don't need to do anything with it. Beta versions of the original
PFP hardware/software calibrated to those black tiles, but some changes
and improvements were made in the black calibration process, and by 1.0
release time, calibration to the black tile was no longer necessary.
