Notes. Thepeak coordinates (from 1280 MHz map ), peak and integrated flux densities of the two H II regions are listed. The integrated flux density in GMRT maps are calculated by integrating above 3σ level. Valuesfor the convolved 1280 MHz map are listed in the second line. For the integrated flux densities, the area probed is kept same as in 610 MHz. Values in parentheses are from the radio maps, generated by setting the “robustness parameter” to −5 and no uv tapering.(⋆) The peak positions of the GMRT maps are consistent with the 1400 MHz (VLA) map (within 5.5′′) and the 4.8 and 8.6 GHz (ATCA) maps (within 2.5′′). Error in integrated flux has been calculated following the equation from Sánchez-Monge et al. (2013), , where σ is the rms noise level of the map, θsource and θbeam are the size of the source and the beam, respectively, and σflux-scale is the error in the flux scale, which takes into account the uncertainty on the calibration applied to the integrated flux of the source. For GMRT maps uncertainty in the flux calibration is 5% (Lal & Rao 2007).
