| | It is often said we must rely on projections from computer simulations of earth's climate since we have no other earth on which to experiment. That is not actually true since we have observations upon a number of planetary objects in our solar system that also have atmospheres. This is brought home by a paper,...

| | Context. Frequency analyses are very important in astronomy today, not least in the ever-growing field of exoplanets, where short-period signals in stellar radial velocity data are investigated. Periodograms are the main (and powerful) tools for this purpose. However, recovering the correct frequencies and assessing the probability of each frequency is not straightforward. Aims: We provide a formalism that is easy to implement in a code, to describe a Bayesian periodogram that includes weights and a constant offset in the data. The relative probability between peaks can be easily calculated with this formalism. We discuss the differences and agreements between the various periodogram formalisms with simulated examples. Methods: We used the Bayesian probabili...
