upstream version of refblas3 package

[Kamaraju Kusumanchi <kamaraju@bluebottle.com>]

Can someone tell me where the upstream version of the refblas3 package is
located? Looking at refblas3-1.2/debian/copyright says that the package is
downloaded from ftp://ftp.netlib.org/blas/blas.tgz . However when I
downloade blas.tgz from the above location, it is different from
refblas3_1.2.orig.tar.gz

$ du blas.tgz refblas3_1.2.orig.tar.gz
104     blas.tgz
696     refblas3_1.2.orig.tar.gz
$ md5sum blas.tgz refblas3_1.2.orig.tar.gz
7e6af7022440d8688d16be86d55fb358  blas.tgz
15061ad22364aa30b9be607262dd3050  refblas3_1.2.orig.tar.gz


Where am I going wrong?

thanks
