Radio continuum image at 1.4 GHz of the region surrounding the pulsar PSR J18091917 constructed using the C and B configurations of the JVLA. The intensity scale is based on a square root relation in units of mJy beam-1. The final beam size is 8.̋3 × 4.̋4 with a position angle of ~–170°. The noise level is 0.17 mJy beam-1 without considering attenuation of the primary beam. The names of SNRs and HII regions lying within the field are indicated. The location of PSR J18091917 is shown with a yellow plus sign, while the best-fit position of the centroid of HESS J1809193 is indicated with a green cross. The white dashed circle denotes the measured extension of the VHE source in terms of the sigma (rms) of a symmetric 2D Gaussian fit to the TeV data (Renaud et al. 2008).
