1D radial profiles from the corresponding 2D maps. Left: intensity map of NGC 1553 constructed using a MUSE datacube over the wavelength range 480–580 nm. To extract the 1D profiles, we employed a rectangular pseudo-slit of width 8 arcsec and a step size of 1 arcsec along its length. Right: 1D radial profile of V (a), σ (b), h₃ (c), and h₄ (d) along the white rectangular pseudo-slit as shown on the left panel. The vertical dashed line in each profile signifies the position of the central slit. Typical median errors are V_err ∼ 6.1 km s⁻¹, σ_err ∼ 8.1 km s⁻¹, h_3, err ∼ 0.028, and h_4, err ∼ 0.033.
