Travel Time Analysis
   
 On the top graph every dot represents the median residual for one month of data. The green line is the overall median; the orange line shows the standard deviation (smad) based on the median absolute deviation (mad), whilst the red line shows twice the standard deviation (2 * smad).
The bottom graph shows the number of residuals for each month. The red columns show the number of residuals whose median (for that month) is outside two standard deviations from the overall median (2 * smad).
Red dots indicate a possible clock error.

Amplitude analysis
  
 On the top graph every dot represents the median value for that month of data.
The green line is the overall median; the orange line shows the standard deviation (smad) based on the median absolute deviation (mad), whilst the red line (if present) shows twice the standard deviation (2 * smad).
The bottom graph shows the number of observations for each month. Any red columns show those observations whose monthly median value is greater than twice the standard deviation (2 * smad) from the overall (running) median (shown in the top graph by red dots).
Red dots indicate a possible calibration error.
