CS is defined as you note and varies from configuration to configuration
within a sample depending upon the "size" of the specimen (quotes since
this size may reflect actual physical size or unscaled camera
magnification).
During the Procrustes superimposition, configurations of points are
scaled (coords/CS) so that they all have CS=1 (= are the same size)
after Procrustes.

Hi all! I am a beginner in geometric morphometrics and I need some
help. In the scaling step of Procrustes superimposition, the
literature say a Centroid size (CS) is the square root of the sum of
squared distances between landmarks and their centroid. But I found
also in papers that Centroid Size=1. I did not understand, if someone
can help me please? Thanks
