Thank you for your suggestion. Do you have any recommendation for point cloud lidar merger?

Hi, I am trying to merge 3 lidar feed. Lidar point cloud topics are working fine. When I tried to run ira_laser_tool node it is working but it is not subscribing to my lidar topis? I have add rostopic list, rosnode info. Also, asking for other tools like laser_merger?

rostopic list:

/laserscan_multi_merger/parameter_descriptions

/merged_cloud
/rosout
/rosout_agg
/scan_multi
/sensor1/points
/sensor2/points
/sensor3/points
/tf
/tf_static

Thanks for help in advance!!!! If there any other options available like ira_merger tool.
