We provide seismological data from a huddle test in Fürstenfeldbruck in August 2019 that was realized by University of Potsdam (PI: Eva Eibl) in collaboration with BGR (PI: Stefanie Donner) and LMU (PI: Felix Bernauer). 5 rotational sensors (blueSeis-3A) and 3 seismometers (Trillium Horizon 120s Nanometrics) were installed on a decoupled basement in a building of the Geophysical Observatory Fürstenfeldbruck. The seismometers were isolated with black foam rubber and white cotton. We recorded passive seismological data for one week and recorded noise, coherent noise sources and the August 29, 2019 ML 3.4 Dettingen earthquake. The aim of the seismic experiment is to compare the performance of rotational sensors and seismometers with respect to different coherent and incoherent noise sources. The noise level, spectral content of the coherent noise and back azimuth of the Dettingen earthquake was further investigated for all sensors using correlation, coherence analysis and probabilistic power spectral densities in Izgi et al. (2021). Waveform data are available from the GEOFON data centre, under network code X3 under CC-BY 4.0 license.
