Header is ASCII format and contains information stored when the file was initially *.lif.raw.bin written (e.g. date, total depth, max signal, gps, etc., and any information entered by the operator).All raw waveforms are appended to the bottom of the file in a binary format. *.lif.plt Stores the plot scheme history(e.g. callout depths)for associated Raw file. Transfer along with the Raw file in order to recall previous plots. *.lif.jpg Ajpg image of the OST log including the main signal vs. depth plot, callouts, information, etc. Data export of a single Raw file.ASCII tab delimited format. No string header is provided for the *.lif.dat.txt columns (to make importing into other programs easier). Each row is a unique depth reading. The columns are: Depth, Total Signal (%RE), Ch1%, Ch2%, Ch3%, Ch4%, Rate, Conductivity Depth, Conductivity Signal. Summing channels 1 to 4 yields the Total Signal. A summary file for a number of Raw files.ASCII tab delimited format. The file contains a string *.lif.sum.txt header. The summary includes one row for each Raw file and contains information for each file including: the file name, gps coordinates, max depth, max signal, and depth at which the max signal occured. An activity log generated automatically located in the OST application directory in the 'log'subfolder. *.lif.log.txt Each OST unit the computer operates will generate a separate log file per month.A log file contains much of the header information contained within each separate Raw file, including: date, total depth, max signal, etc. Common Waveforms (highly dependent on soil, weathering, etc.) Diesel Gas Kerosene Motor Oil
