Limb profiles often require some mental gymnastics. Transposing the plot L-R, so that the PA (Watts Angle) increases from L-R, gives the attached image. Does it match James’ Silhouette?

It’s tricky to identify the required PA when we need to work from the N point of lunar images presented at various orientations, such as from my alt-az mounted Mak.
