SGP/SWATS/E4 - Sensor failures, 5cm and 15cm W

The temperature rise readings from the 15-cm depth on the west profile were incorrect from 
20040212:1500 to 20040217:0800. This also caused the matric potential and water content 
data for the 15-cm depth to be incorrect.

The temperature rise readings from the 5-cm depth on the west profile were incorrect from 
20040217:2300 to 20040218:1900. This also caused the matric potential and water content 
data for the 5-cm depth to be incorrect.

Use east profile data.
