CO(2−1) moment maps from the ALMA Band 6 data cube of NGC 4593, created using CASA. Top left: Integrated intensity (moment-0 map) showing the spatial distribution of the line flux, with a total calculated flux of approximately 100 Jy km/s. The colour bar represents the intensity scale in Jy km/s per beam units. Top right: Intensity-weighted velocity (moment-1 map) with scale bar units in km/s, tracing gas velocities and kinematics within the galaxy. Bottom left: Intensity-weighted velocity dispersion (moment-2 map) with scale bar units in km/s. Bottom right: ALMA Band 6 continuum image (background) displaying the dust distribution, overlaid with CO(2−1) emission moment-0 map contours from ALMA observation Project ID: 2017.1.00236.S.
