*The %area parameter of the color sensor is in the range of 0% to 100%, and it was used to specify the percent area of pixels over
the surface of a particle that must have the (greenish) white color corresponding to that of spodumene grains visible on some rocks.
† RD =relative density. The RD parameter is in the range of 0 (least dense) to 230 (most dense).
‡ The %area parameter of the DE-XRT sensor is in the range of 0% to 100%, and it was used to specify the percent area of pixels
over the surface of a particle that must have a pixel density of the value specified by the RD parameter.
