Examples of the SED of two LPBLs, namely ID=2440 and ID=2061. The solid line represents a logarithmic parabolic fit, including the radio, infrared, optical, and X-ray data points, which does not match the infrared and optical data. These are instead well reproduced by a three-point fit excluding the X-ray datum (dot-dashed line). The case shown in the left panel indicates that the X-ray emission is likely dominated by the inverse-Compton component; that in the right panel highlights how the upper limit to the X-ray flux leads to a large overestimate of the synchrotron peak frequency. The grey line represents an elliptical galaxy template normalized in W2 and the grey dots show data collected from the ASDC.
