Sample usage ( BODY ) =Moreover, pulsars with intermediate-to-high ecliptic latitudes would be sensitive to the n e variability dictated by the solar cycle in this framework, as we expect the LoS to be passing through the fast wind during the periods of solar minima (causing the n e lows that we observe in Fig. 12 ), and during the solar maxima, the LoS possibly passes through a mixture of fast and slow wind (hence denser than the fast wind alone), causing the highs in n e shown in Fig. 12 . 5.3.1. Comparison with the OMNI data We compared the n e time series of a subset of pulsars with the proton density at 1 AU 12 provided by the OMNI database ( Papitashvili et al. 2014 ), as obtained with the in-situ spacecraft solar wind Electron Proton Alpha Monitor (SWEPAM) for the Advanced Composition Explorer ( ACE , see McComas et al. 1998 ) and DISCOVR .
