Table 2. List of semilandmark curves used in these analyses.

Curve	# Semi-landmarks	Description/Notes
Nasal Aperture	17	From rhinion counterclockwise around nasal aperture, through nasospinale, down right and up left.
Nasospinale – Prosthion	4	Follows midline.
R./L. Premax-Max Suture	11	From Premax-Max Superior to Premax-Max Inferior along suture.
Dorsal Rostrum	23	From right M1-2 contact superiorly across rostrum midline to left M1-2 contact, orthogonal to alveolar plane.
R./L. Orbit	13	Orbital margin from Zygo-Max Superior laterally through Frontomalare Orbitale, medially through Mid-Torus Inferior and hamulus/notch to dacryon.
R./L. Temporal Margin	10	From Frontomalare Temporale to Zygo-Temp Superior along temporal margin.
R./L. Inferior ZygomaticMargin	9	From Zygo-Max Inferior to Zygo-Temp Inferior along inferior-most margin of zygomatic.
R./L. Alveolar Margin	10	Along outer margin of alveolar process from Distal M3 to Mesial P3.
