357 GNGTS 2021 S essione 2.2 the user can choose to exclude specific records, or the related stations and/or events, by selecting the corresponding spectrum from the waveforms table or from the figure and excluding it from the combination. The final results can be downloaded in two types of file formats (ASCII and HDF5) along with a table (JSON format) collecting all the metadata associated with the combination. REXELweb will be maintained and improved with new features to better meet user requirements and design provisions. Acknowledgement REXELweb has been developed in cooperation with RELUIS and Università degli Studi di Napoli Federico II, in the framework of the 2019-2021 ReLUIS-DPC research program WP18 funded by the National Department of Civil Protection and coordinated by Roberto Paolucci (Politecnico di Milano).
