Lower panels: spatial profiles of the 2D spectrum of XID2028 (left) and XID5321 (right) of the continuum flux (solid curves) and in the proximity of [OIII]λ5007 emission line (long dashed curves). Both continuum and [OIII]λ5007 wavelength range profiles are normalized to unity. The dotted lines shows the demarcations of the three regions from which the apertures were extracted (denoted with a, b, and c). Upper panels: HST/ACS F814 image of XID2028 (left) and J-band UltraVista image of XID5321 (right) showing the position and orientation of the 0.9′′ slit and the spatial locations of the three apertures.
