The tracker at failed to wake up on 12/26/2012.  The problem persisted throughout the time 
range specified.  On 1/3/2013 the tracker was power cycled and returned to normal 
operation.  

The tracker malfunction adversely affected the data from the direct normal instrument 
(short_direct_normal). Also affected is the diffuse shaded global data (down_short_diffuse).
