FKB/GNDRAD/M1 - Incorrect calibration coefficient applied to up_short_hemispheric 
instrument
DataStreams:fkbgndrad20sM1.a0, fkbgndrad60sM1.b1, fkbgndradM1.00
Description:
An incorrect calibration coefficient was applied to the up_short_hemispheric instrument 
(PSP) for the specified time period.  Changes in the ARM PSP calibration procedure now 
generates two differnt calibration coefficients for the same instrument, Cf(non "IR 
corrected")and Cfc("IR corrected").  CFc should have been applied to this instrument when CF was 
used.
The affected PSP is S/N 34292F3 CF=117.61, CFc(now applied)=116.07W/m2/mV
