Image ( 45 . 0 × 45 . 0 $ 45{{\overset{\prime\prime}{.}}}0\ {\times}\ 45{{\overset{\prime\prime}{.}}}0 $) of the central region of NGC 1566 at 6597 Å (observed frame) taken by MUSE on 2017 October 23. Each arm of the compass is 10 . 0 $ 10{{\overset{\prime\prime}{.}}}0 $ in length. Spectra of the nucleus and the H II region were extracted using apertures of 1 . 0 $ 1{{\overset{\prime\prime}{.}}}0 $ and 0 . 5 $ 0{{\overset{\prime\prime}{.}}}5 $ in radius, respectively, indicated by the blue and magenta circle. The inlay shows the zoomed-in nuclear region ( 10 . 0 × 10 . 0 $ 10{{\overset{\prime\prime}{.}}}0 \times 10{{\overset{\prime\prime}{.}}}0 $). Each arm of the compass is 2 . 0 $ 2{{\overset{\prime\prime}{.}}}0 $ in length. The color scale is logarithmic in order to enhance weaker emission features.
