+FIXME: It is not know how this table works. It seems that labels are wrong: **YA_min** and **YB_min** are repeated twice, may be they are **YA_max** and **YB_max**.
 White balance is probably applied as a series of linear transformations to the **four raw values** captured by te **[[wp>Bayer_filter|Bayer filter sensor]]**. The four channels are **Red**, **Green-on-red**, **Blue** and **Green-on-blue**, each transformation consists of a multiplier coefficient (slope) and an offset.
