TWP/QCRAD/C1/C2/C3  - error in qc flags

In the qc_down_short_diffuse_hemisp field, QC failures from the test indicated by bit_13, 
"data failed tracker off test", were set incorrectly as bit_9, "GSW2SumSW (93 > SZA > 75 
and SumSW > 50; GSW/SumSW < 0.85 or GSW/SumSW > 1.15)".  Solar tracker failures are 
correctly indicated in the aqc_down_short_diffuse_hemisp field. 

In the qc_short_direct_normal field, QC failures from the test indicated by bit_10, "data 
failed tracker off test", were set incorrectly as bit_9, "GSW2SumSW (93 > SZA > 75 and 
SumSW > 50; GSW/ SumSW < 0.85 or GSW/SumSW > 1.15)".  Solar tracker failures are correctly 
indicated in the aqc_short_direct_normal field. 

This is a software problem in the VAP that impacts all dates for which a solar tracker 
failure occurred prior to 20100608 for each facility.  The 20020312 start date was chosen 
because the DQR system can not link multiple start/end date/times with multiple facilities 
within the same report.  As a result, the latest start date corresponding to C3 was 
chosen. The actual start dates for which this problem could have occurred for each facility 
are as follows:

C1:  19961010
C2:  19981029
C3:  20020312

Please note that if a solar tracker failure is not indicated by the 
aqc_down_short_diffuse_hemisp and/or aqc_short_direct_normal fields you can ignore this DQR.
