IMU Origin at the Pixhawk

Hello everyone,

I wanted to know the origin of the inertial reference frame of the Pixhawk Cube V3. I am trying to align the pitot tube with the IMU origin with some offset. But I couldn’t find the IMU origin details in the manual. There are 3 IMU’s, I know the origin point for the MPU 9250. Should I align with this one or consider other points?
