MLOC Plots


Because of the quantity and complexity of the output from mloc, graphic display of information has proven to be of extreme importance in evaluating relocation analyses. All image files (plots) in mloc are created by the Generic Mapping Tools (GMT). If mloc is run on a computer without an installation of GMT, plotting can be turned off with the command gmtp, but it is a severe handicap.

At the end of a run mloc creates the requested GMT scripts and then executes the scripts to produce PostScript files, which are finally converted to PDF. The main GMT scripts are saved in a folder for each run named ~_gmt_scripts, so that they can be edited and re-run (e.g., for publication purposes) if desired. For display on this website the example plots have been converted to JPEG format.

A variety of other plots are available, in most cases requested by a command. A suite of such plots that are commonly utilized is described in the Summary Plots section. These include the base plot, the direct calibration raypath plot and a set of travel-time plots controlled by the pltt command.

Other important types of plots are:
