I would like to use your RS2 for my experiments, and I have a question about the purchase.

For my experiment, I want to tilt the RS2 with the camera mounted at an arbitrary angle (e.g. Roll 0°, Pitch 30°).  I read RS2’s documentation and confirmed that it can be controlled via Linux PC.

My question is which coordinate system does RS2 refer to?

In documentation, RS2 can be set to any angle(ex: roll 20.1deg).

I would like to know to which coordinate system this roll angle is referenced.

Is it a coordinate system based on the earth's surface(aka world coordinate), or is it based on the angle when the RS2 power button is pressed?

If RS2 is taking it with respect to the ground surface, I would appreciate a quantitative assessment of how reliable the RS2 angle acquisition is.
