Example barlens galaxy, NGC 1350. Left panel: the bar region of the 3.6 μm image. Marked are the structure components measured in this study: “bl” refers to barlens, “thin bar” is the bar region outside the barlens, and “nucleus” refers to possible small bulge in the central regions. Right panel: the contours of the same image. Lines indicating the orientations of the bar (blue line), barlens (red line), and the disk line-of-nodes (dashed line) are over-plotted. Black crosses show the points selected to measure the size and orientation of the barlens by fitting an ellipse to these points.
