If they are published separately, why is IMU frame rate so low? and has so much delay?

In normal situation, the IMU would publish > 100 Hz with <1 ms delay, and images would be published at 30 Hz with maybe ~50 ms delay, meaning that the warning would never happen (that would be impossible that we didn't receive yet the IMU when we receive the image 50 ms later than the IMU stamp).
