Left: HGPS significance map (obtained with a correlation radius of 0.1°) centered on HESS J1458−608. The size and spectral extraction radius R_spec of HESS J1458−608 are represented by the dashed and solid yellow circles, respectively. The blue and white circles correspond to the 95% position uncertainties of the Fermi-LAT cataloged sources, while the green cross represents the position of PSR J1459−6053 (associated with 4FGL J1459.5−6053). Right: PMN map at 4.85 GHz with the radio cataloged sources outside the ON regions represented in red. The flux extraction regions appear in white (R_ON1 and R_ON2) and the FWHM of the PMN is represented at the top left of the image. The yellow circles are the same as those in the left panel.
