Notes. is the uniform distribution and is the Jeffreys distribution (log-flat) between xmin and xmax. is the normal distribution with mean μ and scale σ, and is the modified Jeffreys distributiona. The modified Jeffreys distribution is defined as Around HARPS mean velocity, − 30.8907 km s−1. Only in models with a linear drift. Only in models with quasi-periodic kernel.
