I don't see how that could be read to mean anything other than the
FOV used
with the actual measuring instrument.
If the field of view of the measuring instrument was indeed 2 degrees
from say 1cm away? It would be measuring colour from a somewhat small
area. About 0.3 mm diameter or about a pixel.
It will be referring to the 2 degree or 10 degree observer.
(Calculated from the spectral data from the spectrophotometer and xyz
2 degree or xyz 10 degree data)
