From the instrument team:  This commanding will adjust matrix strip
thresholds, raise Telescope A threshold and disable noisy Matrix strips.
Several Matrix detector strips on Telescopes A & B became noisy after
last week's solar event which coincided with orbital perihelion that
brings higher temperatures which in turn raise detector leakage currents
and cause the increase in electronic noise.  During data analysis we
identified the noisy strips and developed the strategy to adjust Matrix
detector thresholds and disable some Matrix detector strips on both
Telescopes in order to improve instrument performance.  Total: 54 strips
disabled, 2 strips unusable.
