Note:
EVENT locations can be input as either discrete Cartesian receptors (XR=, YR=) or
as discrete polar receptors
(RNG=, DIR=). Events that are specified in the file
generated by the AERMOD model (CO EVENTFIL card) are always given as discrete
Cartesian coordinates. Discrete polar receptors are assumed to be relative to an
origin of (0,0).
