The entry in the molczan.tle file gives a single dimension of .30m
and a magnitude 0f 9.5. The UOSAT-12 web page gives the mass as 325
or 350Kg. These numbers are not consistent. It implies a density of
14 gms/cc, somewhat larger than pure mercury. I think the size is
copied from older uosat  microsatellites for which it is true.
unfortunately the web page doesnt give dimensions of uosat-12,
I have sent an e-mail to the pr person mentioned on the web pages
about this ommission.
