That is the number I quote for a DOTA pretrain, and it is the official Task 1 score. On the Hub the field is eval_task1_map50. Say which images the number was measured on, then give the percentage. How a rotated box becomes that percentage is below. AP50 counts a match when the rotated rectangles overlap by half. Here is how that percentage is built.
