Interval	Begin	End	Days	Description	|\bar{v}x|	sigmavx	\bar{n}p	sigmanp
1	01 Jan 1995	29 Jul 1995	209	before minimum; quasi-periodic HS streams	457	125	6.5	4.7
2	15 May 1996	16 Aug 1996	93	solar minimum; predominantly LS wind	398	52	9.0	4.9
3	08 Jan 1997	09 Jun 1997	152	after minimum; LS wind; some streams	403	75	9.1	6.0
4	23 Aug 2000	15 Feb 2001	176	solar max; variable wind; some HS streams	430	100	7.0	6.0


aThe units of proton velocity vx and density np are km/s and particles per cubic centimeter, respectively. The rms values are defined by sigmavx2 = <(vx - \bar{v}x)2>, where \bar{v}x is the sample mean (GSE coordinates) and the angle brackets denote a time average over the given interval. HS, high-speed; LS, low-speed.
