In Münchmeyer et al. 2019 magnitudes scales for Northern Chile have been derived with a focus on low uncertainties. The data set consists of three parts. First, a version of the IPOC catalog with the derived magnitude scales ML and MA and their uncertainties. Second, the attenuation functions for different waveform features. Third, the full matrix of features and the resulting single station magnitude predictions.The underlying IPOC catalog was obtained from Sippl et al. (2018). Detailed data description is provided in the README and in Münchmeyer et al. (2019) to which these data are supplementary material.
