A zoomed-in view of NGC1566, one of the 66 galaxies. Left: Continuum-subtracted intensity image of the galaxy in the F770W MIRI band. The 2σ CO intensity contours from PHANGS-ALMA are represented in black. Right: PAH cloud structures identified by SCIMES color-coded by their F770W intensities. The green, blue, and red contours indicate the spiral arm, bar, and central region masks, respectively. The interarm region in this case consists of the remaining clouds that are not enclosed by the contours. The number of PAH clouds identified in this galaxy is represented in the bottom right. The color bar at the top of the image shows the 7.7 μm intensity range of the identified clouds.
