SED of MRC 0251−273. Black solid line shows best fit total model, green and purple dashed line is north and south synchrotron lobes, respectively. Black dashed-dotted line shows the blackbody and the black dotted line indicates the AGN component. The colored data points are sub-arcsec resolution data and black ones indicate data of low resolution. Green pentagons are north synchrotron, purple hexagons are the south radio component and the blue diamond indicates the ALMA band 6 detection. Filled black circles indicate detections (> 3σ) and downward pointing triangles the 3σ upper limits (Table A.9).
