SGP/SIRS/E6 - Questionable data due to Ice Storm damage

Several SIRS readings at E6 readings have appeared questionable since the ice storm in 
early January.  Starting on 01/13 maintenance found the E6 tracker inoperative. It was reset 
and put back into serivice.  Shortly after, on 01/16 data from the DSH instrument (PSP) 
became questionable possibly due to obstructed or failed ventilator fan.  On 02/10 1645 
GMT maintenance found the DSH instrument ventilator fan failed - the fan was replaced,  
the E6 tracker was also realigned.  Due to early january ice storms, the tracker alignment 
issues and a failed ventilator fan - All tracker mounted and global DS instrument 
measurements are suspect for this time frame.
