A series of graph routines were developed to assess the SEISAN catalogue data. The following graphs are available for QC purposes:

  • Events by Hour - Histogram

  • Events by Month - Histogram

  • Events by Year - Histogram

  • Number of stations - Histogram

  • RMS of time residuals - Histogram

  • ML vs Time - Scatter plot

  • ML vs Year - Scatter plot

  • b-value - Cumulative histogram and line

  • Error Ellipse

  • Error Ellipse (No depth errors)

  • GAP - Histogram

  • Longitude Error - Histogram

  • Latitude Error - Histogram

  • P-Phase Residuals - Histogram

  • S-Phase Residuals - Histogram

  • ML Residual - Plot with error bars

  • Time Residual - Plot with error bars

  • Wadati plot - Line and points

These graphs are accessible through a dropdown list in the graph window. For the graphs displaying error ellipses, an option is available to save the ellipses to a shapefile.
