The (right ascension (RA), declination (Dec)) coordinate difference (burst relative to counterpart) is shown with an ellipse indicating the 1σ error calculated as the quadrature sum of errors in the two sources. VLBA and EVN positions are indicated, with 1σ errors smaller than the symbols. The centroid of the Gemini optical counterpart is shown (red dot) with an estimated 1σ error circle of 100 mas (red) from fitting and radio-optical frame tie uncertainties.

                        Extended Data Figure 2 VLA spectrum of the persistent counterpart to FRB 121102.The integrated flux density Fν is plotted for each epoch of observation (listed by MJD) over a frequency range ν from 1 GHz to 25 GHz. Error bars represent 1σ uncertainties. The spectrum is non-thermal and inconsistent with a single power law.
