Details/Specifics of Change:

The following updates of the calibration coefficients were implemented
for:

NOAA-16 AVHRR

Ch_1_lo = 0.05367*count - 2.069, count<498.96
Ch_1_hi = 0.1567*count - 53.24, count>498.96

Ch_2_lo = 0.05761*count - 2.176, count<500.16
Ch_2_hi = 0.1697*count - 58.25, count>500.16

NOAA-17 AVHRR

Ch_1_lo = 0.05475*count - 2.191, count<501.12
Ch_1_hi = 0.1607*count - 55.30, count>501.12

Ch_2_lo = 0.06584*count - 2.585, count<500.73
Ch_2_hi = 0.1960*count - 67.85, count>500.73

Ch_3_lo = 0.03135*count - 1.322, count<501.37
Ch_3_hi = 0.2198*count - 95.96, count>501.37

on February 8. These coefficients are intended to be optimal on February
22.

The first orbits to be processed with the updates are:
