Notes. Our periodicity candidates sorter according to the local significance (same as Table A.1) with their 4FGL source name, long-term trend, and the dates for the next four gamma ray cycles. The – in the Long-term Trend column means that no trend was inferred and in the other columns mean that there is no predicted cycle.
