Unique elements for the UVMRP/insitu data entity.

Calibrated UV/visible irradiance in Watts/meter2. 

See the UVMRP_README for headers common to all entities.

Column headers:
•	www(Total/Diffuse/Direct)
•	UV = 300/305/311/317/325/332/368(Tot/Dif/Dir)
•	VIS = 415/500/615/673/870/940(Tot/Dif/Dir)

QC codes (0 OR semi-colon delimited list):
•	lvX = low voltage for channel X
•	dr = dirty diffuser
•	bm = shadowband motion problem; only total irradiance available
•	vg = electronic noise in the signal due to aging of the components or interference from adjacent instrumentation
