All NOAA-17 AMSU-A 1b data users

Details/Specifics of Change:
It was noticed that channel 7 appears to have a problem which affects all
detector views (warm, cold, and earth views). In an effort to partially
correct the problem, we will open the cold target calibration limits to
stop data gross filtering.
The update for NOAA-17 CPIDS has been promoted to operations. The
first orbits to be processed are listed below.
