Broadband SEDs of 1ES 0647+250 for the different observing campaigns described with one-component and two-component SSC emission models. Top left: 2009–2011. Bottom left: 2014. Top right: 2019. Bottom right: 2020. Filled blue dots correspond to the MWL simultaneous data of each period. Empty dots represent the archival data extracted from the SSDC database (https://www.ssdc.asi.it). The dotted lines correspond to the fitted one-component SSC model. Black lines represent the total two-component SSC model. The dashed and dotted-dashed lines correspond to the blob and core components of the two-component model, respectively.
