On this page we assemble additional material (worksheets, programms, ...) for evaluating the observations. Most of the material will be linked on the corresponding pages.

Work sheets
- comp2Mercurypositions.xls (version 2016-05-16) for the calculation of the distance to the Sun by combinating two positions of Mercury measured simultaneously at distant sites. As illustration the sheet containes one pair of (theoretically determined) positions.
- All positions measured at the same site may be copied into tableofMercurypositions.xls (version 2016-05-09). The sheet calculates the linear fit to these positions. Saved as ".txt" format the data can be evaluated with one of the programs below.Example sheets have been uploaded via our data transfer page.
- Sheets with simulated position data
Programs
- The exact mesurement of Mercury's positions on the Sun's disc may be done with evaltransitpicts (version 2016-05-16).
- As comp2Mercurypositions.xls the program calcparallax (version 2016-05-17) calculates the Astronomical Unit by comparing two simultaneously measured positions of Mercury.
- With comptransitof mercurypos (version 2016-08-08) complete position data of two distant observers can be combined in order to get the best possible measure of the Astronomical Unit from their observations. If no suitable measures for this comparation are available theoretical geocentric data may be taken instead (see above).
- eclipses (or its German version), (Windows-) programs which simulate eclipses and transits
