Surface brightness contour map of three sources : PGC 56121, PGC 56125, and J15491758 +214951179. Left: The contour levels plotted are 4σ, 5σ, 7σ, 11σ, 16σ, 22σ, 34σ, and 55σ above the background level on far-UV image. Regions highlighted in pink represent areas of higher flux density and are likely associated with active star-forming regions, while the green shaded areas denote more diffuse emission, possibly due to gas with lower luminosity. Objects analyzed in this study are outlined by white dashed regions. Right: Contours derived from the FUV data overlaid on the SDSS r-band image for a comparison and to identify star-forming and brighter regions.
