Detailed Description

Chamber lengths and the reported pressure profile (CN-1, CN-12).

CN-1: the chamber "length" is barrel + cone and leaves out the 1.5 Rt entrance arc; the solved
      contour was rebuilt from a stored length that went stale (it drew L* 1.0035 for 1.0000),
      and the cone/arc junction carried a duplicate vertex.
CN-12: the pressure profile was invented -- 1.10 Pc at the injector "for pintle injectors" and
      a throat at Pc -- where the throat static pressure is Pc (2/(g+1))^(g/(g-1)).
Geometry references are hand geometry on the drawn contour (1.5 Rt arc, 45 deg cone).
