1.8 Geometrical analysis of the plan: first
elaborations
A first elaboration has been made in order to study the
geometry and the hypothetical criteria of the scheme
and layout of the plan.
For example, in the tetraconco the four circumferences
generated by the four sectors of the exedra have been
defined through the minimization of the square
deviation between the surveyed points (about thirty)
and the circumference interpolated through the same
points (fig. 4).
The hypothesis that the exedras belong to a
circumference appears to be logical a posteriori either
for the radial deviations obtained between the real
position of the observed points and the interpolated
circumference, or for the root-mean-square deviation of
the four calculated radiuses, or for the fact that the four
radiuses are similar. The four interpolated
circumferences which are obtained from the points
belonging to the curvilinear parts of the eight bearing
piles, considered two at a time corresponding to the
relative exedras, set out circumferences nearly
