The analogy branch is located in my repository. So you need to add my
repository as a remote one:
git remote add xenomai-abe git://xenomai.org/xenomai-abe.git
git fetch xenomai-abe


Now, the branch should be available:
git branch -r
...
    xenomai-abe/analogy
...

You just have to create a new branch on your repo:
git branch --track xenomai-abe/analogy analogy
