Crosstalk -
Coeff for the crosstalk R,G,B matrix (for Method C of BT2446). Value 0.0 to 0.33.
Will apply a crosstalk matrix on RGB before XYZ matrix convertion.
Avoid value over 0.3 in 8 bits mode. 0.0 means no crosstalk between R,G,B.
Very useful!
I'm gonna post the link here to the relative documentation so that others can see what this is for: https://www.itu.int/dms_pub/itu-r/op...2019-PDF-E.pdf (go to page 19 if you are curious).

In particular, the crosstalk matrix is applied such that saturations of linear signals are reduced to achromatic to avoid hue changes caused by clipping of compressed highlight parts.
