Common objects#
In this section of the configuration file, we include all the physical objects whose properties are going to be shared among several models, and that are independent of the datasets under analysis. For example, the orbital period of planet is a common parameter and its value will be the same regardless of the model selected to analyze the data (e.g. the planet must have the same period if measured with either transits or radial velocities). As another example, the rotational period of a star and the decay time scale of active regions can be considered common parameters, while the amplitude of stellar activity will depend on the dataset under analysis as it changes with wavelength.
Note
Not all the physical parameters defined in a common object will be employed in the modelling, but only those required by the models listed in the model section of the configuration file and recalled in the model subsection of each dataset under the input section
