A statistical walk through the IAU MDC database

The IAU MDC database is an important tool for the study of meteor showers. Trough the history, the amount of data in the database for particular showers, and also their extent, varied significantly. Thus, a systematic check of the current database (as of. 1st of June, 2014) was performed, and the results are reported and discussed in this paper. The most obvious one is that the database contains showers for which only basic radiant data are available, showers for which full set of radiant and orbital data is provided, and showers with data span anywhere between. As a lot of current work on meteor showers involves D-criteria for orbital similarity, this automatically excludes showers without the orbital data from such work. A test run to compare showers only by their radiant data is performed, and was found to be inadequate in testing for shower similarities. A few inconsistencies and typographic errors were found and are shortly described here.
