full_mag0.ps    'Full' hig--res field showing gray--scale magnetogram and
        flow vectors (from local correlation tracking; blue for upflows, red
        for downflows)

full_divflowmag0.ps  <-- good overview, but rather crowded plot
     'Full' (tracked) field showing magnetogram, supergranulation cell outlines
        (in red, based on divergence maps of flow field), and flow vectors
        (from local correlation tracking; blue for upflow, red for downflow)

part_magflowdiv0.ps <-- quarter field, same as above, although different
colours
     Quarter field of view, showing magnetogram, supergranulation cell
        outlines (in green, based on divergence maps of flow field), and
        flow vectors (from local correlation tracking; blue for upflows,
        red for downflows).

full_clusters_divflowmag#.ps for #=1,2,3,4
                (I'ld recommend these as good summary plots)
     Four quarter fields of the high-res field showing:
        gray scale    of magnetogram, showing only the clusters exceeding the
                           noise level
        yellow lines  the supergranular cell boundaries (based on divergence
                           of the flow)
        vectors       correlation tracking flow field, blue for upflow
                           (positive divergence), red for downflow (negative
                           divergence)
        green circles the ultimate location at which corks embedded in the
                           time-averaged flow field converge

-- Perhaps useful for a presentation where you want the flows and fields
separately in viewgraphs that you can put on top of each other:

aas_#_0.ps for #=1,2,3,4 :
          1) detail of high resolution magnetogram (quarter field)
          2) outlines of supergranulation cells (based on cell finding
               algorithm than uses the divergence of the flow, as determined
               from correlation tracking. Also shown are the flow vectors
               (blue for upflows, red for downflows), the central locations
               of the upflows (blue dots), and the final collection points
               of corks passively flowing in the surface flow.
          3) [Probably not of interest] Voronoi tesselation: assuming all
               supergranules to be of equal strength and with only radial
               outflow from centers, shown by yellow dots, downflows occur
               midway between upflows.
          4) 'Cleaned' magnetogram (showing only strongest concetrations)
               and overlay of flow cell boundaries.


They are rather large and optimized to the resolution of our Kodak printer.
I've also put gzip-ped copies (with extensions *.ps.gz) in the directory to
speed up data transfer.

Let me know whether you want anything else: it's (relatively) easy to
change the contents of these plots.
