Cylindric sundial for these parameters: Radius of the cylinder is 0.57 times the distance R of the shadow-casting point from the plane, i.e. radius = 875.27 The line perpendicular to its tangent plane points at:l0 azimuth 167.0 degrees, angular height 0.0 degrees, The latitude of the place is 49.5 degrees The local time is 9.0 min ahead of the shown time The shadow-casting point is at distance R=1545.60 from the plane The coordinates origin at the sub-gnomon point, X goes horizontally to the right, Y upwards. Pole X=-2703 Y= -245 Pole X= 350 Y= 1774 Length of the shaft projection is 1808 Length of the shaft is 2379 Analema for the plotted time T=12.00: MM-DD X Y 1- 1 387 -474 1-11 359 -510 1-21 336 -568 2-
