Results of Contact time Measurements

The contact times measured by the participants of this project yield quite satisfying measures of the Astronomical Unit, i. e. of the distance to the Sun!

By copying the contact measurements into the actual versions of the corresponding worksheets evaluationofcontacttimes1+2 and evaluationofcontacttimes3+4, the following line fits and median values of the solar parallaxe are calculated:

contact 1	contact 2

π_Sun=8.89"	π_Sun=8.87"
1AU=148060000 km	1AU=148310000 km

contact 3	contact 4

π_Sun=8.83"	π_Sun=8.29"
1AU=148990000 km	1AU=158750000 km
