5 GHz VLBA image of the radio counterparts of the γ-ray sources 1FHL J0043.7+3425 (left panel), classified as a FSRQ, and 1FHL J0648.9+1516 (right panel), classified as a BL Lac. The beam size is 1.6 mas × 4.1 mas and 1.3 mas × 3.2 mas, respectively. Levels are drawn at (− 1,1,2,4...) × the lowest contour (i.e., at 1.2 mJy/beam for the source 1FHL J0043.7+3425 and at 1.4 mJy/beam for the source 1FHL J0648.9+1516) in steps of 2. The noise level is 0.31 mJy and 0.37 mJy, respectively.
