Unclear definitions of range_bandwidth and azimuth_bandwidth in abstracted metadata

In the abstracted metadata (viewed via the Metadata Window) there are two fields called range_bandwidth and azimuth_bandwidth. The description column says these are “total range bandwidth” and “total azimuth bandwidth”. This is not clear:
Is the range_bandwidth a) pulse bandwidth, b) total processed range bandwidth, or c) range look bandwidth ?
Is the azimuth_bandwidth a) illuminated Doppler bandwidth, b) total processed Doppler bandwidth, or c) azimuth look bandwidth ?
The description column could be improved to better explain what these parameters are.

I’m not sure ifthese fields have universal definitions @lveci could you comment?
