Histograms of the properties of the freckles: the observed Hα flux (log erg cm⁻² s⁻¹) (top left); the [N II]6583 Å/Hα ratio (upper right); log extinction at Hβ, c from Hα/Hβ (centre left); N_e ([S II]) (cm⁻³ (centre right); T_e ([N II]) K (bottom left); T_e ([S III]) K (bottom right); The vertical bar in the plots shows the corresponding value for the large- scale nebular emission of NGC 4361 from the MUSE central field, but excluding the area of the freckles. Note: each histogram only plots the available number of values of each parameter (listed in the title to each plot as (#) ); for the extinction, N_e and T_e histograms only the values from the A and B quality spectra are shown.
