After plate solve the image and get Gaia catalogue for example, then the correspondence between this catalogue and the sources in the fluxes array is not clear. Seems logic that should be row by row, means the target in the row 0 in the catalogue should corresponds to the row 0 in the fluxes array (see attached picture), but I am not 100% sure.
