Six methods for analyzing the completeness of seismic data, of course based on catalogs, without involving the completeness assessment related to station detection
These methods are the most commonly used, and you can explore the functions by inputting different parameters. Recently, some Mc calculation methods designed for different directories have also emerged; you may read relevant literature to find the ones best suited to your needs.
