EXAMPLE UNFILTERED AC-9 DATA FILE showing the Hydrolight Standard Format for ac-9 data.                                 
(These data were obtained in conjunction with files AC9_filtered.txt and Hydroscat6.txt.)                                
The absorption (a) and beam attenuation (c) values of this file are used by Hydrolight                                  
to model the total (particles + CDOM) a and c (pure water values were subtracted out when 
processing the raw data).  If the option of having a filtered ac-9 file is selected in the 
front end, Hydrolight subtracts the filtered a values from these a values to get particle a. 
The original data were binned in 0.5 m depth bins starting with the first recorded depth;                               
the depths shown are the average depth of the data in each bin.  Column headers (depth in m; and and c in 1/m):
