TWP/SMET/C1 - Upper winds failure

The upper wind instrument was inoperative resulting in constant wind direction and speed.  
A failed cable was replaced.

• Upper sensor, wind direction standard deviation(up_dir_sd)
• Upper sensor, wind direction vector average(up_dir_vec_avg)
• Upper sensor, wind speed maximum(up_spd_max)
• Upper sensor, wind speed arithmetic average(up_spd_arith_avg)
• Upper sensor, wind speed vector average(up_spd_vec_avg)
• Upper sensor, wind speed minimum(up_spd_min)
• Upper sensor, wind speed standard deviation(up_spd_sd)

TWP/MPL/C1 - Scope Temp is incorrect

Scope temperature is incorrect because the probe failed/was missing.

Ignore the scope temperatures and assume the true values are acceptable.

• Telescope temperature(scope_temp)

• Telescope temperature(scope_temp)

• Telescope temperature(scope_temp)

TWP/MPL/C1 - Energy monitor registers 0

When the instrument was returned to service following replacement of the scope temperature 
sensor, the power supply was not turned on; hence system was not operating, though the 
software was.
