Unknown values

Bjorn Gimle recently posted information on two decaying
rocket debris objects:
22325 Express 1 SL-12 r/b     0.76 m2
23015 Raduga 31 SL-12 r/b     0.78 m2
I assume the fractional number is the effective surface area
in square meters.
The OIG Satellite Situation Report Volume 35, Number 6,
dated June 30, 1995 found on the
<ftp.physics.ox.ac.uk/pub/sat> site lists an "RCS" for:
22325 as 0.4566, and
23015 as 0.8780
Question #1.  Would Bjorn or others know what the
correlation is between the two values, if any?  Since there
is no linear releationship, maybe they are not related.  I
could not find "RCS" defined in the report.
Question #2.  An additional question that has been bugging
me for some time is the four elements found on line 0 of
some elsets (Ted Molczan's and some others).  What are those
four elements describing?  Again, I have never come across a
description for what those values are for.
Thanks in advance,   Jeff Hunt <jhunt@eagle1.eaglenet.com>
