Stellar kinematic maps of NGC 1553 derived from the MUSE data cube using the GIST pipeline. Top: LOS stellar velocity (V) distribution (left) and corresponding stellar velocity dispersion (σ) map (right). The nuclear disc is outlined by the solid black ellipse, while the dashed ellipse indicates the hot inner lens. Bottom: third (h3, left) and fourth (h4, right) Gauss-Hermite velocity moments. The overlaid contours, extracted from the MUSE intensity maps, are spaced at uniform intervals of 0.2 mag. The orientation is such that the north is up, and the east is to the left.
