The flux profiles taken above plage and umbral regions. The 1550 Å and Ca II H plage cross-cuts are the dashed (green) and dotted (blue) lines, respectively. The 1550 Å and Ca II H umbral cross-cuts are the dash-dot (red) and solid (black) lines, respectively. The intensities have been normalised to the largest counts/sec value in the umbral and plage cross-cuts for each filter. The reduced emission in the Ca II H umbral cross-cut at ~ 1′′ along the slit is due to the Wilson depression of the sunspot.
