Also,
That wiki link has incorrect information, leading an unsuspecting person to
believe that

fn_Pigm( ).x | fn_Pigm( ).u | fn_Pigm( ).red
to get the red value of the color vector
fn_Pigm( ).y | fn_Pigm( ).v | fn_Pigm( ).green
to get the green value of the color vector
fn_Pigm( ).z | fn_Pigm( ).blue
to get the blue value of the color vector
fn_Pigm( ).filter | fn_Pigm( ).f
to get the filter value of the color vector
fn_Pigm( ).transmit | fn_Pigm( ).t
to get the transmit value of the color vector

When:
there is no .f,
..t is for filter,
and .transmit is the only dot notation to access the 5th term.

Edit or delete that, or add an erratum note?
