Spectral index distribution over radio lobes of 4C 14.11 using astrophysical data in FITS format

The goal of this paper is to investigate the flux and spectral index distribution FR II radio galaxy 4C 14.11. We focused on indices over lobes, as well in their hot spots. For that purpose, we used publicly available observations given at 1450 8440 MHz. Particularly, Leahy's Atlas radio-emitting double sources, Jodrell Bank Centre for Astrophysics Manchester, NASA/IPAC Extragalactic Database. found non-thermal (synchrotron) radiation dominates areas lobes. Distinction between spots rest lobes are much smaller than flux. also inner parts both $\alpha$ flat average significantly higher 1.2, indicating 14.11 old AGN.
