Following this timetable it is possible to know times of transit and their locations on the Line. Locations are expressed in Centesimae Partes of the pinhole's height, and are indicated on the line from 33 to 220. Each of those numbers are related to the zenithal distance z of the Sun at the meridian by the formula CP=100·tan(z). z is also written in degrees on the west side of the Line: 78=100·tan(38°) in the photo of March 29, 2006 solar eclipse.
