Ch_1_hi = 0.1594*count - 54.18, count>498.96
Ch_2_lo = 0.05900*count - 2.229, count<500.16
Ch_2_hi = 0.1738*count - 59.66, count>500.16
NOAA-17 AVHRR
Ch_1_lo = 0.05527*count - 2.212, count<501.12
Ch_1_hi = 0.1623*count - 55.83, count>501.12
Ch_2_lo = 0.06658*count - 2.614, count<500.73
Ch_2_hi = 0.1982*count - 68.62, count>500.73
Ch_3_lo = 0.03207*count - 1.352, count<501.37
Ch_3_hi = 0.2248*count - 98.16, count>501.37
NOAA-18 AVHRR
Ch_1_lo = 0.05198*count - 2.050, count<501.00
Ch_1_hi = 0.1550*count - 53.30, count>501.00
