Accessing sensor data from a ROS node

[santiagorg2401]

Hi, I hope you're all doing well,

With the recent development, I am working with sensor data, but, I want to access it from a ROS Node, I know that in order to log variables one needs to list the variables in hover_swarm.launch, but, I do not know which variables to log, I need to get the readings of the laser sensor of the flow deck and the height calculation from the Loco Positioning system (for the development of a obstacle avoidance algorithm with ROS nodes), do you know where can I find a list with the available logging parameters?, and do you also know how to "ignore" the flowdeck readings in the state estimator?

Thank you, have a nice day.
