SGP/EBBR/E20 - Soil Temperature and Soil Moisture  #4 Measurements Incorrect

The ts4 sensor reported 99999 values because the sensor leads were loose.  Soil moisture 
#4 reported low values (steady 16%) during this time period.

The sensible and latent heat fluxes were not affected by this problem, only
soil temperature and soil moisture #4.  See soil temperatures and soil moistures from sets 
#2, #3, and #5 for correct values (note: soil temperature #1 was having problems during 
the same time).
