Information about obserr.txt

[lkugler]

Hi,
does anyone have an idea what the columns in obserr.txt describe?
And why are there 3 rows for one Obs-type?

Example:

   0.5   0.5   0.5   0.5   0.5      BOGUS      TEMP SENSOR ERRORS   
   0.5   0.5   0.5   0.5   0.5        : 
   0.5   0.5   0.5   0.5   0.5        : 
   0.0   0.0   0.0   0.0   0.0       NU 
   0.0   0.0   0.0   0.0   0.0        : 
   0.0   0.0   0.0   0.0   0.0        :

NU stands for "not used" I guess.
The entries shall be RMSE values of measurement errors including representation error, right?

Thanks,
Lukas
