Problem about the sensor frequency.

[Gatsby23]

Dear Professor:
Thank you very much for developing this ros-tool to help us collect the simulation data. However, there are something bothering me with the sensor's frequency. I want to collect the data to prove my LIO algorithm. Like the document shows, I close the synchronous_mode and set fixed_delta_seconds 0.001. The lidar's sensor_tick is 0.1 and the imu's sensor_tick is 0.005. However, the data can't used in all the lidar slam system. It's always drift.
PS: In default value, the system is working well with lidar slam system like(A-LOAM). But I can't use the 20HZ to prove my LIO-System.
I really don't know how to do it, so begging for your help.
Yours
Qi Wu

I have the same issue, did you fix it？
