-  <figcaption><strong>Figure:</strong> Results of applying Euler inversion with a window size of 12 000 m and a window step of 2400 m to the
-aeromagnetic data from Rio de Janeiro, Brazil. Estimated source locations and structural indices obtained from Euler
-inversion are shown as triangles (𝜂 = 1), squares (𝜂 = 2), and circles (𝜂 = 3). The colour of each symbol represents
-the estimated depth below the surface of the Earth (topography). Also shown are the total-field anomaly flight-line
-data, the contours of the post-collisional magmatism and alkaline intrusions (solid black lines) and dykes (dashed
-lines). The purple squares highlight the A, B, C, and D anomalies that are discussed in the text.</figcaption>
