"""
JroPattern class creates an object to represent the useful parameters for beam mode-
lling of the Jicamarca VHF radar.
Parameters
----------
pattern = An integer (See JroAntSetup to know the available values) to load a prede-
fined configuration. The default value is 0. To use a user-defined configuration
pattern must be None.
path = A string giving the directory that contains the user-configuration file. PATH
will work if pattern is None.
filename = A string giving the name of the user-configuration file. FILENAME will
work if pattern is None.
nptsx = A scalar to specify the number of points used to define the angular resolu-
tion in the "x" axis. The default value is 101.
nptsy = A scalar to specify the number of points used to define the angular resolu-
tion in the "x" axis. The default value is 101.
maxphi = A scalar giving the maximum (absolute) angle (in degree) to model the ante-
nna pattern. The default value is 5 degrees.
fftopt = Set this input to 1 to model the beam using FFT. To model using antenna
theory set to 0 (default value).
getcut = Set to 1 to show an antenna cut instead of a contour plot of itself (set to
0). The defautl value is 0.
dcosx = An array giving the directional cosines for the x-axis. DCOSX will work if
getcut is actived.
dcosy = An array giving the directional cosines for the y-axis. DCOSY will work if
getcut is actived.
eomwl = A scalar giving the radar wavelength. The default value is 6m (50 MHZ).
airwl = Set this input to float (or intger) to specify the wavelength (in meters) of
the transmitted EOM wave in the air. The default value is 4m.
