Two-component Gaussian fitting of the 1.6′′ × 1.6′′ rest-frame nuclear spectrum of NGC 5643 for the Hβ,[OIII]λ4959 and [OIII]λ5007 emission lines. The [OIII]λ5007 lines in the nucleus shows an asymmetric blue wing, reproduced with blueshifted Gaussian components. The systemic components have a FWHM_sys = 286 ± 6 km s^-1, while the outflowing components have a centroid shifted by v_0,out = −200 km s^-1 and a FWHM_out = 590 km s^-1. The projected velocity at the 10th percentile of the overall emission-line profile is v₁₀ = −430 km s^-1, confirming the presence of outflowing, high velocity gas from the nuclear region.
