Radio continuum emission at 1.5 GHz. The white crosses indicate the positions of the pulsars PSR J1856+0245 and PSR J1857+0300. The white square shows the region mapped in the C band with the VLA and the contours represent the TeV emission below 1 TeV extracted from H. E. S. S. Collaboration (2018) with values of 1.5, 2.0, 2.7, 3.5, and 4.5 in units of 10⁻¹³ ph cm⁻² s⁻¹. The angular resolution is 17.′′38 × 15.′′ 51, PA = 6°.87 and the noise is 0.7 mJy beam⁻¹. The color scale is expressed in Jy beam⁻¹.
