Header is ASCII format and contains information stored when the file was initially <br />*.lif. raw.bin written (e.g. date, total depth, max signal, gps, etc., and any information entered by the operator). All <br />raw waveforms are appended to the bottom of the file in a binary format. <br />*.lif.pit Stores the plot scheme history (e.g. callout depths) for associated Raw file. Transfer along with the <br />Raw file in order to recall previous plots. <br />*.lif.jpg A jpg image of the OST log including the main signal vs. depth plot. callouts, information, etc. <br />Data export of a single Raw file. ASCII tab delimited format. No string header is provided for the <br />columns (to make importing into other programs easier). Each row is a unique depth reading. The*.lif.dat.txt columns are: Depth, Total Signal (%RE), Chl %, Ch2%, Ch3%, Ch4%, Rate, Conductivity Depth, <br />Conductivity Signal, Hammer Rate. Summing channels 1 to 4 yields the Total Signal. <br />A summary file for a number of Raw files. ASCII tab delimited format. The file contains a string <br />*.lif.sum.txt header. The summary includes one row for each Raw file and contains information for each fileincluding: the file name, gps coordinates, max depth, max signal, and depth at which the max signal <br />occured. <br />An activity log generated automatically located in the OST application directory in the 'log' subfolder. <br />Each OST unit the computer operates will generate a separate log file per month. A log file contains*.lif.log.txt much of the header information contained within each separate Raw ftle, including: date, total depth, <br />max signal, etc. <br />Common Waveforms (highly dependent on soil, weathering, etc.) <br />Diesel Gas Kerosene Motor Oil <br />SL Rvcd 2019.01.21
