Flux comparison between the official BGPS flux catalogue and the Hyper flux estimation. The comparison includes 796 sources extracted from the public available BGPS v2 catalogue in the Galactic range 20° ≤ l ≤ 28°. The fluxes in the BGPS v2 catalogue are estimated with Bolocat within three different aperture radii: 20′′, 40′′ and 60′′ (for details of the BGPS v2 catalogue generation see Ginsburg et al. 2013). Hyper fluxes have been evaluated for all the sources fixing the three different apertures. The agreement is very good for both faint and bright sources at each aperture, with less than 1% of the source with a flux difference ≥50%.
