Daily sampling of magnetic data of MGS during the mapping phase. Expressed in percentage of available data taking into account a continuous nominal maximum sampling. The upper part presents the 12 time series used for our calculations using both proxies: proxy-MGS-1, 6 time series of 125 days (blue); proxy-MGS-2, 2 time series of 210 days (red); proxy-ACE, 4 time series of 200 days.
