% Elevation Mask

% Notes:
% 0 <= AZ <= 360 deg
% -90 <= EL <= 90 deg
% The first azimuth element, e.g. 10, covers azimuths from 0 - 10 degrees.
% The second azimuth element, e.g. 20, covers azimuths > 10 and <= 20
% degrees.  Therefore, the cut-off elevation corresponding to the first
% azimuth element is constant for that range of azimuths.

mask.az = [360];
mask.el=  [0];
