How to Reference

SOFiA Coordinate System

SOFiA is based on a spherical coordinate system as follows:
AZ denotes the azimutal angle in a range of (0-2pi(. Whereas AZ=0 is defined to be the front direction and AZ=pi to be the rear direction.
EL denotes the elevation angle in a range of (0-pi). EL=0 points upwards, EL=pi/2 points to the horizontal plane and EL=pi points downwards.
All angles are in RAD.
r is the radius in meters (if needed/specified).
