Notes. The first four columns refer respectively to the method version used, the size of the postage stamps cutouts, whether the data were denoised (den) or not (raw), and whether a functional form was used for the PSF (func) or a star postage stamp (star). The Q column denotes the quality factor as originally published in the leaderboard. The ℳ/2 and columns indicate respectively the average multiplicative and additive biases over all image sets. The NN23 methods was submitted in the post-challenge, after the post official galaxy challenge deadline.
