MODL.srs - fits to fault slip rates
Items: 1. Longitude 2. Latitude 3. Observed slip rate (mean or minimum) 4. Observed slip rate (zero or maximim) 5. 1-sigma uncertainty 6. Calculated 7. Residual 8. Residual divided by sigma 9. M* or S** (M indicates min/max was fit, S indicates mean/sigma was fit) 10. Block 1 11. Block 2 12. Azimuth of slip rate measurement 13. Total rate at that point (not corrected for azimuth) 14. Input file number 15. Data label 16. input file name
* If item #9 is M then #3 is the minimum slip rate, #4 is the maximum slip rate, and #5 is the assigned 1-sigma uncertainty for the inversion (one-quarter the min/max range). The residual is zero if the calculated slip rate #6 falls between the min and max observed. If the calculated is outside the observed range, the residual is how far it falls outside the range.
** If item 9 is S, then #3 is the mean slip rate, #4 is not used, and #5 is the assigned 1-sigma uncertainty in the slip rate.
