SED of MRC 0156−252. Black solid line shows the best fit total model, green and purple dashed line represents the northern lobe and synchrotron emission from the core, respectively. Black dotted line indicates the AGN component. The colored points are data which have sub-arcsec resolution and black ones indicate data of lower resolution. Green pentagons represent the fluxes of the radio core, purple hexagons are the fluxes of the northern radio lobe, the blue diamond indicates the ALMA band 6 detection which coincides with the radio core and the magenta square is the second ALMA detection of the northern radio lobe. Filled black circles indicate detections (> 3σ) and downward pointing triangles 3σ upper limits (Table A.5).
