Please do not forget to enter the Polynomials P2 - P5 inside the coefficient area.

And please be aware of the multiplexing principle inside the Logbox SD, it will take at least a full

between the measurement taken of the first channel and the measurement taken on the fourth
channel. (Albedo measurements should be taken on the same time interval.)
