View of the simulated loop from the side as seen in EUV and X-ray observations. Panels a–c: view at the original resolution of the numerical model, panels d and e: images downsampled to the plate scale of the instruments. From top to bottom: synthetic emission for the 171 Å and 211 Å AIA bands integrated along the y-axis, emission as would be measured with the Al-poly filter of XRT, degraded synthetic emission in the 211 Å band taking into account the pixel size of the AIA instrument of 0.6″, degraded emission for XRT with a pixel size of ∼1″. The synthetic emission has been integrated along the line of sight perpendicular to the loop axis. See Sect. 3.4.
