Map not correctly matched

[ManuelSanchezMo]

Hi;

I'm trying to use the node to merge two point clouds, one coming from a Ouster OS0 and another coming for an OS1 mounted in two huskies, all simulated in gazebo. When I run the node it subscribes to the point clouds, and generate a map, but it is not correct matched, as you can see:

I am using it on Ubuntu 18.04, with the default configuration. Have you any idea why this happens?
