That ‘s how long the routine analysis of data took with pencil, paper, and logarithmic tables. Thus when Wilhelm Olbers discovered the minor planet Vesta in 1807 and gathered the necessary observations, his friend Gauss needed almost 10 hours to hand calculate its orbit. That achievement astonished many less gifted astronomers of the time, who might have labored days to work out the orbit of a newfound comet. How different things are today! Gauss‘s method of orbit determination, presented in Chap. 11 of this book, runs to completion on a horne computer in a few seconds at most. The machine will issue its accurate results in less time than it takes to key in the observations. In this book, alandmark in the youthfulliterature of astronomical com puter algorithms, Oliver Montenbruck and Thomas Pfleger cover many topics of keen interest to the practical ob server. For me its most remarkable feature is the library of interrelated program modules, aIl elegantly written in PAS CAL.
