NIM/SKYRAD/M1 - Unknown problem with PIR1
DataStreams:nimskyradM1.00, nimskyrad20sM1.a0, nimskyrad60sM1.b1
Description:
Spikes in Shaded 1 occur frequently during this time period, resulting in differences b/t 
shaded1 and shaded2 exceeding 20W/m2.  Instrument connections were checked and a spare 
PIR instrument was tried in the place of PIR1 (shaded1).  After returning the original PIR1 
to its original location data again looked good and very close to PIR2.  Problem appears 
resolved but exact cure is unknown.
