NOAA-16 AVHRR
Ch_1_lo = 0.05451*count - 2.102, count<498.96
Ch_1_hi = 0.1591*count - 54.07, count>498.96
Ch_2_lo = 0.05886*count - 2.223, count<500.16
Ch_2_hi = 0.1734*count - 59.52, count>500.16
NOAA-17 AVHRR
Ch_1_lo = 0.05518*count - 2.208, count<501.12
Ch_1_hi = 0.1620*count - 55.74, count>501.12
Ch_2_lo = 0.06645*count - 2.609, count<500.73
Ch_2_hi = 0.1978*count - 68.48, count>500.73
Ch_3_lo = 0.03197*count - 1.348, count<501.37
Ch_3_hi = 0.2241*count - 97.85, count>501.37
NOAA-18 AVHRR
Ch_1_lo = 0.05243*count - 2.067, count<501.00
Ch_1_hi = 0.1563*count - 53.75, count>501.00
Ch_2_lo = 0.06098*count - 2.402, count<500.00
Ch_2_hi = 0.1830*count - 63.75, count>500.00
on July 11. These coefficients are intended to be optimal on July 25, in
the middle of the two scheduled updates.*
