I'm in the process of constructing a multi-camera (x3) system for some Pose estimation work I'm doing. I would like to confirm the drawn x (red), y(green), z(blue) frame on the camera is correct, as it relates to the .json file manually created during the calibration process.

Additionally, unlike all of the examples I've seen so far, our setup could have cameras that are rotated relative to eachother. I wanted to confirm if the 'rotation{}' part of the .json file is in degrees or radians.
