1. I now have better values for the soil densities than my first cut at looking at the data (which only used the first set of gravimetric measurements). I'm now using the mean of all measured values at 3-6cm. (There sometimes is a lot of variation between these measurements.)
2. The soil motes apparently had a "watchdog timeout" that reset power on the soil sensors rather frequently. I believe that this occurred at all sites sometime, and, when bad, happens every ~4hours:50minutes. Each time, the TP01 reported values of 0 until it was able to take another reading. These 0 values were averaged in to each TP01 variable, generating lots of spikes. A range check on the TP01 Vheat and Tau63 values has now been added to eliminate these zeros. The covars are being rerun now.
