In this table you get
for each of timed contacts:
- the value of the average distance of the Earth from the Sun
(astronomical unit, AU) calculated from your measures,
- the corresponding value of the angle under which would be
seen the Earth radius from the center of the Sun (Solar parallax Π),
- their shifts from the exact values Δ(AU) et Δ(Π),
- the percentage of error of these values.
At the bottom of the
table, you get the average value of the whole set
of measurements.

results with regard to all the measures
The graph below shows
the distribution of the measures of the
astronomical unit performed at this moment:
- The number of observers for every slice of values of the
astronomical unit is represented by a vertical bar.
- Tour own measure is represented by a green line.
- The exact value by a red line.
