Hopefully quick question: In the DP1 Object Schema there are a series of columns of the form {ugrizy}_apXXFlux where XX is 03, 06, 12 etc e.g. g_ap03Flux which have the description "Flux within 3.0-pixel aperture. Forced on g-band. ". I was unable to find a definitive statement as to whether these were XX pixels radius or diameter. I suspect the latter but can this be confirmed, ideally with a pointer to a definitive statement; I also looked at the DP1 Object docs and the linked-to Source detection and measurement overview
Ta muchly,
