Data availability for the stations of the network 3A. Availability of the recordings for each station as a function of time (blue lines). For clarity only the vertical components have been used. Gaps in the recordings (red) are mainly due to days with weak solar radiation. The figure has been realized using the obspy-scan tool included in the ObsPy package (https://docs.obspy.org/packages/autogen/obspy.imaging.scripts.scan.html).
