SED of MRC 2048–272. The black solid line shows the best fit total model, green and purple dashed lines are the northern and southern synchrotron lobes. Neither the blackbody nor the AGN component are fitted to the upper limits. The colored data points are sub-arcsec resolution data and black ones indicate data of low spatial resolution. Green pentagons are northern synchrotron, purple hexagons are the southern synchrotron component and the blue triangle shows the ALMA 6 3σ upper limit. Filled black circles indicate detections (> 3σ) and downward pointing triangles the 3σ upper limits (Table A.21).
