Photometry profiles of NGC 1272. Top Left: Surface brightness profile of NGC 1272 measured from the Euclid VIS image, calibrated to the V band, and corrected for Galactic absorption and cosmological dimming, as a function of the 1/4 power of the semi-major distance A on the sky in arcsec. Bottom Left: Difference ΔSB between the surface brightness profile of NGC 1272 and the surface brightness of the core-Sérsic+Sérsic model. Right: Ellipticity 1 − B/A, where B is the semi-minor axis length on the sky (top) and PA (bottom) as a function of the 1/4 power of A. The solid red lines show the core-Sérsic+Sérsic model. The dashed lines show its core radius. The blue line shows the ellipticity profile of the axisymmetric deprojection. The green line shows the PA profile of the triaxial deprojection.
