thanks for answering.

I have ("bad") odometry but I want to fusion the data to have a better
precision. I tryied the canonical_scan_matcher with success. Doesn't seem to
as easy to do the same with polar_scan_matcher which is more relunctant to
launch.
I'll post on answer.org for precise question. This mail was just to be sure
I wasn't speaking to wall ;) First question there
http://answers.ros.org/question/905/what-is-the-difference-between

BTW I am quite impressed of the precision out of the box of the
canonical_scan_matcher.
