\footnotesize Time resolution measured with data taken in Run 3, for 33 telescopes; the average time resolution is given by the gaussian fit and is $\sigma_{t}$ = 238 ps.

\footnotesize Time distributions for the telescopes: TORI-04, BOLO-03, PATE-01 and TREV-01 (respectively located in Piedmont, Emilia Romagna, Sicily and Veneto), measured with data taken in Run 3; the distribution and the time resolution before and after TS correction are shown.

\footnotesize $\Delta t$ distribution for one of the EEE telescopes (TORI-03), showing the gaussian fit and the time resolution $\sigma_{t}$ = 221 ps. The data used in this case are from Run 2 and the \textit{time slewing} (TS) correction is not applied.

\footnotesize $\chi^{2}$ distribution for one of the EEE telescopes (TORI-03, located in Piedmont) before any cut is applied. A zoom in the range $\chi^{2}$ = [0-20] is included.

\footnotesize Time distributions for the telescopes: TORI-04, BOLO-03, PATE-01 and TREV-01 (respectively located in Piedmont, Emilia Romagna, Sicily and Veneto), measured with data taken in Run 3; the distribution and the time resolution before and after TS correction are shown.

\footnotesize Efficiency vs. applied HV (corrected for standard $p$ and $T$) of the middle MRPC of 9 EEE telescopes. The red arrow indicates the usual value chosen as working point.

\footnotesize Distribution of the efficiency obtained at the plateau (corrected for standard $p$ and $T$) of the middle MRPC for 31 EEE telescopes. An efficiency better than 90\% is reached by 77\% of the network.

\footnotesize Transverse spatial resolution measured with data taken in Run 2 and Run 3 for 46 telescopes of the EEE network.

\footnotesize Top view of a MRPC chamber, showing the 24 copper strips, the 2 FEA at the edges of the chamber and the connectors where 2 DC/DC converters providing the HV (top left in blu and bottom right in red) are plugged in.

\footnotesize Correlation between TOT and the difference between the measured time and the time expected on the concerned chamber. The correction to be applied to each hit time is obtained from this distribution (for each single chamber). The distribution of one chamber of the telescope BOLO-01 (located in Emilia Romagna region) is shown here as an example.

\footnotesize Efficiency vs. strip for 2 EEE telescopes (located in Emilia Romagna region and Sardinia.

\footnotesize Time distributions for the telescopes: TORI-04, BOLO-03, PATE-01 and TREV-01 (respectively located in Piedmont, Emilia Romagna, Sicily and Veneto), measured with data taken in Run 3; the distribution and the time resolution before and after TS correction are shown.

\footnotesize MRPC inner structure.

\footnotesize Track multiplicity distribution of one of the EEE telescopes (SALE-01, located in Campania); the applied cut is $\chi^{2}$ $<$ 5 in this case.
