Column density (panel a), dust temperature (panel b) and chi-square (χ² ) (panel c) maps of the region associated to H II regions. 1280 MHz GMRT radio emission is shown as contours. The contour levels are same as those plotted in Fig. 6. The dashed line on the H II regions shows the projections, the column density variation which is used to understand the morphology of the ionized region in a later section.
