• Select the data type you want to filter (Fig. 2.2-2b).
• To decimate the selected data type, click the Edit button in the Decimate area (Fig. 2.2-2c).
  • Enter a number in the Show every <N> points to limit the display to every Nth data point.
  • Click the Apply. button
• To smooth the selected data type, click the Edit button in the Gaussian Smoothing area (Fig. 2.2-2d).
  • Select the type of rolling window: Points or Depth (cm)
    • Enter the number of points in 
  • Select the display option: Smoothed only or Original & Smoothed
  • Note: you can change the color of the smoothed trace in the Display Preferences > Set Colors
  • Click the Apply. button
• To cull the selected data type, click the Edit button in the Cull area (Fig. 2.2-2e). You have to cull type options:
  • The first type of cull is to Cull <x> cm from core tops.
    
    • Enter the interval in cm to be culled from each core in the data set.
  • The second type is to to Cull outliers data values greater and/or less than a given value.
    • Enter a value for Cull data values > x
    • Enter a value for Cull data values < x
  • Click the Apply button.

Note: 

• Data filters are applied to the data from all cores for a specified data type. For a more specific filtering of known intervals with severe core disturbance, etc., you have the option to apply a file with those intervals specified in the Correlator Downloader application, at the time of data download.
• At this time, data culling can only be specified for top of cores (to remove data from “exotic” material washed down from higher up in the hole). A future version will include culling from core bottoms (“exotic” material “sucked in” when the piston core was removed) and culling from section ends (“edge effect”).
• Some odd behavior has been observed when deleting a cull filter under certain circumstances, and this has not yet been repaired (no user pressure). An easy workaround is to re-load the data.
