127   Note that conversion from a float or RGBE color space applies a conversion
128   of 179 lumens/watt (for CIE or melanopic output) or 412 (for scotopic output),
129   and the reverse happens for conversion from XYZE input to RGB or RGBE output.

131 + If a matrix or picture file path is given to the

135 + The

142   Additionally, the
