7.2 Remove duplicates
Catalogs may have duplicate entries referring to the same events. CompiCat allows the user to make search for duplicates and either to delete or to leave intact the candidates for being duplicate entries reported in a given catalog. To open the window for duplicate removal (Remove duplicates) click button .

   The Proximity limits tab of Remove duplicates window allows setting the limits of the temporal, location, and magnitude differences to be use in duplicate search. Specifically, the two catalog entries are considered candidates for being duplicates if all the differences are less than or equal to the selected values in the five Proximity limits boxes. Note the difference in magnitude is related to the Common magnitude, which definition could be adjusted by the user in the same way as Common magnitude from 7.1 Convert magnitudes

The tab Criterion for autoremoval allows switching the program from Interactive to Automatic removal of duplicate entries by choosing the appropriate radio-button in the Duplicate removal section. Moreover, in the Automatic mode the user has an option to define the rule of unique identification and removal of catalog entries. Specifically, the user defines the criterion for choosing one of the two candidate entries by magnitude and, in case of the equality, by their order (the program simply removes either first or second entry marked with the appropriate radio-button). The magnitude value greater (or value less) indicates higher priority for the entry to remain in the output catalog; in these cases, the choice of magnitudes in the checked boxes on the left define the priority for the unique magnitude determination. Each of the magnitude indices maximum greater, maximum less, minimum greater, minimum less, average greater, average less applied to the checked magnitudes defines higher priority for the entry to remain in the output catalog.
In the Interactive mode  the user has an option to follow the automatic suggestion, or to chose the alternative entry, or leave both entries intact. The two candidates for removal are shown in the lower part of either Proximity limits and Criterion for autoremoval tabs. The button Next confirms the choice and proceed to the next candidates for duplicate removal.
The button Apply confirms the choice from the Proximity limits and Criterion for autoremoval tabs and runs duplicate removal procedure.
The button OK confirms the choices already made in the Interactive mode and, from this very point, continues duplicate removal procedure in the Automatic mode. The button OK is also used to accept all the results of the Tool. To rerun duplicate removal anew without saving the current results the user can change some of the Tool parameters and click the button Apply.
The button Cancel is used to cancel all the actions performed by the Tool earlier and closes the Remove duplicates window.
By clicking the Default button the user sets the default values of the Tool. By clicking the Reset button the user can remove all the changes introduced after entering the Tool window. (Note that Reset button during the first usage of the Tool is equivalent to the default values.)
