<TR><TD>The objective: To find the mirror image of the patterns
<UL>
<LI>of the marks pointing up on the <A HREF="plotting.htm">skeleton plot</A>
<LI>with the marks hanging down on the <A HREF="masterchronology.htm">master dendrochronology</A>
</UL>
How to move the skeleton plot (<EM>try it on the right</EM>):
<UL>
<LI>Put the mouse cursor in the <FONT COLOR="gray">gray region</FONT> of the plot
<LI>Click and hold the left mouse button
<LI>Move the mouse left or right
</UL>
How to know when you have a match:
<UL>
<LI>All of the skeleton plot marks -- and even the "b" marks -- should line up with those on the dated master chronology
<LI>The mirror imaging should be visually obvious
<LI>If it's not obvious, the text above the skeleton plot will let you know
</UL></TD>
<TD><APPLET code="PatternMatching.class" WIDTH=470 HEIGHT=330></APPLET></TD></TR></TABLE>
<P><EM>Good idea</EM>: Click the "Try Again" button to have more chances to match patterns of a skeleton plot and master chronology<BR><BR>
<EM>Note</EM>: When <A HREF="SkeletonPlot18.htm">you try skeleton plotting for yourself</A>, you can move the master by mouse clicking within the time-series part (<FONT COLOR="gray">shaded gray above</FONT>) and moving left or right
