NSS.GHRR.NL.D05312.S1312.E1507.B2644445.GC
NSS.HRPT.NL.D05312.S1638.E1650.B2644646.GC
NSS.LHRR.NM.D05312.S1236.E1248.B1753838.WI
NSS.GHRR.NM.D05312.S1412.E1557.B1753940.WI
NSS.HRPT.NM.D05312.S1558.E1612.B1754040.WI
NSS.GHRR.NN.D05312.S1429.E1615.B0242728.GC
NSS.HRPT.NN.D05312.S1617.E1628.B0242828.GC
The new coefficients are:
NOAA-16 AVHRR
Ch_1_lo = 0.05407*count - 2.085, count<498.96
Ch_1_hi = 0.1578*count - 53.64, count>498.96
Ch_2_lo = 0.05825*count - 2.200, count<500.16
Ch_2_hi = 0.1716*count - 58.90, count>500.16
NOAA-17 AVHRR
Ch_1_lo = 0.05484*count - 2.195, count<501.12
Ch_1_hi = 0.1610*count - 55.39, count>501.12
Ch_2_lo = 0.06650*count - 2.611, count<500.73
Ch_2_hi = 0.1979*count - 68.54, count>500.73
Ch_3_lo = 0.03173*count - 1.338, count<501.37
Ch_3_hi = 0.2224*count - 97.11, count>501.37
NOAA-18 AVHRR
Ch_1_lo = 0.05095*count - 2.009, count<501.00
Ch_1_hi = 0.1519*count - 52.24, count>501.00
Ch_2_lo = 0.05953*count - 2.346, count<500.00
Ch_2_hi = 0.1786*count - 62.24, count>500.00
These coefficients are intended to be optimal on November 26, in the
middle of the two scheduled updates.
