Registered CVMs
CVM names and naming conventions within UCVM can be confusing, largely because the CVM model names and abbreviations have changed during UCVM development, and there is not consistent use throughout the software and documentation.
UCVM users need to know the velocity model of interest, and then the abbreviation that UCVM uses to refer to the CVM of interest. The following tables briefly describes the standard CVM models available through UCVM, and the abbreviation used by the UCVM software to refer to each model.

This table shows the standard scientific name for each model (on the left), and the model abbreviations used by UCVM in column 2. It is the abbreviation listed in column 2 that is used to specify the model of interest when calling UCVM. The sections below describe each of these registered models.
