Fig. 3.
Left: spatially resolved Hα emission line map for the BCG of the M1931 galaxy cluster. The colour-bar shows the flux of the Hα line in units of 10−17 ergs s−1 cm−2. Right: Hα equivalent width map measured in Å. The contours correspond to different levels of flux and EW. The white background in both plots corresponds to spaxels with S/NHα < 10. The cross shows the location of the AGN.
