MLOC Depth Codes
mloc uses single-character “depth codes” in a variety of circumstances to carry information on the source of a depth estimate. The recognized codes are listed here:
|c||Cluster default depth|
|d||Teleseismic depth phases|
|e||Engineered (man-made explosion)|
|f||Fault model (InSAR, GPS, etc)|
|m||mloc solution with free depth|
|n||Near-source station readings|
|r||Relocation outside mloc with free depth|
Although the use of depth codes is optional (blank is processed without problems), it is recommended to use them whenever possible.
The depth code “l” indicates a constraint on focal depth from readings at local distance (but still direct, crustal P and S phases), beyond the distance range normally considered appropriate for depth control (for which the “n” flag is provided). This is an advanced topic that requires careful analysis in mloc.
