Rotational Ground Motion Parameters Catalog – General Description
Ground Motion Parameters Catalog contains data from the Seismic catalog and Rotational Ground Motion Catalog through the event ID. That data format can be made using the application Ground Motion Parameters Catalog builder user guide.
The catalog The catalogue is a variable in the Matlab format file and it is kept in a file MAT. The structure is an array with named fields that can contain data of various types and sizes. In the file there is only one variable, the file name and variable name are optional. The format of Rotational of the Rotational Ground Motion Parameters Catalog is prepared in the same manner as the Catalog of seismic events, Ground Motion Catalog, and Ground Motion Parameters Catalog.
The variable describing the catalogue catalog is a vector of structures, consisting of fields:
- field – name of field in the catalogue catalog (text value);
- type – type of field in the catalogue catalog and way of showing the field (numeric value);
- val – column array of values. For the text the column is an array type cell with text fields. For the remaining value, the column is a numeric column.
- unit – description of unit for individual data (text value).
- description – short description of the parameter (text value).
- fieldType – semantic meaning of the field. When some field values are similar/related then fieldType name is entered and for another case [] is entered.
