2D maps of [N II]λ6584/Hα and [S II]λλ6716, 6731 doublet line ratios, and ISM density estimated from the [S II] line ratios. We find a modest indication for higher [N II]/Hα ratios along the north–south direction across the central BCG and for density increase toward the northeast. However, these trends are observed within the uncertainties.
