Top panel:  oxygen and proton speed, as measured, respectively, by the
SWICS and SWOOPS experiment over the November/December 1998 quadrature
days.  A low latitude "fast" wind of about 500 km/s is originating from
the coronal hole identified at photospheric levels in the Fe XIV map
and is followed by a slower wind after the hole passage.  A constant
velocity approximation was used to map the solar wind back to the Sun.

Middle panel:  density ratios of adjacent charge states observed in situ
by the SWICS experiment, over the November/December 1998 quadrature. 
From this ratio, a "freeze-in" coronal temperature can be inferred; the
average values of the ratio are given in the plot only to show that
in situ plasma bears witness of its source down in the corona and gives
additional evidence of the different plasma origin over the
quadrature days.  

Bottom panel:  the ratio of the O VI 1032 and 1037 line intensities as
derived from UVCS observations over the November/December 1998 quadrature.
Because this ratio can be crudely considered as a plasma speed proxy
(higher plasma speeds corresponding to lower ratios) the temporal profile
of the ratio shows that also at coronal levels plasma flows, in the
first days of the quadrature campaign, faster than later on.  Coronal
observations like those from which the plot originated, coupled with
in situ data, such as those shown in the panels above, allow one to
track the conditions of a plasma parcel from coronal out to distances
of the order of a few AU.
