Astronomical-Geodetic Yearbook
The Astronomical-Geodetic Yearbook - also known as the Heidelberg Yearbook in professional circles - was a scientific publication, the tables of which placed a special focus on the astrometry of the planetary system and on astrogeodesy .
It has been published by the Astronomisches Rechen-Institut in Heidelberg since the interwar period and edited together with the Berlin Astronomical Yearbook in the 1940s . Over the next two decades, the content was expanded to around 450 pages and adapted to the advances in computing technology. Like the Berliner Jahrbuch, it was part of an international cooperation in the early 1960s - see Astronomical Ephemeris .
Geodesists particularly valued a. the Polaris ephemeris (for azimuth measurements ) and the numerous auxiliary tables, etc. a. for the different coordinate systems , for reductions and astronomical refraction .
