5BZQJ 0555+3948. Top right panel: Sky-Explorer view, showing 3FGLJ 0556.2+3933 indicated as a red cross, while 5BZQJ 0555+3948 is outside the error circle associated with the γ-ray signature from 3FGL database. Blue and red circles represent X-ray and radio detections in this region. Top left panel: TS map, E > 1.0 GeV with improved position for the γ-ray signature; Black dashed lines show the 68%, 95%, and 99% confinement region for the γ-ray signatures. The dashed magenta circle corresponds to the 3FGLJ 0556.2+3933 position, while the green circle is centered on the position of 5BZQJ 0555+3948 marked as black cross. Bottom panel: SED for 5BZQJ 0555+3948, where the blue bump template assumes z = 2.365.
