Variation of the radii of the Moffat Core components of the PSFs in J (black curves) and K_s (red curves) bands across the FoV with respect to the GS distance in arcseconds. The continuous lines refer to the elongated radii of the Moffats. The dashed lines refer to the non-elongated radii of the Moffats. The non-elongated radii have been considered constant in this simplified model.
