argosim.plot_utils.plot_antenna_arr(array, ax=None, fig=None, title='Array')[source]#

Plot antenna array.

Function to plot the antenna array in ground coordinates.

Parameters:

  • array (np.ndarray) – The antenna array positions in the ground.

  • ax (matplotlib.axes.Axes) – The axis to plot the antenna array. For plotting on a specific subplot axis.

  • fig (matplotlib.figure.Figure) – The figure to plot the antenna array. For plotting on a specific subplot axis.

  • title (str) – The title of the plot.

Return type:

None

argosim.plot_utils.plot_baselines(baselines, ax=None, fig=None, ENU=False)[source]#

Plot baselines.

Function to plot the baselines in uv-space.

Parameters:

  • baselines (np.ndarray) – The uv-space sampling positions.

  • ax (matplotlib.axes.Axes) – The axis to plot the baselines. For plotting on a specific subplot axis.

  • fig (matplotlib.figure.Figure) – The figure to plot the baselines. For plotting on a specific subplot axis.

  • ENU (bool) – If True, plot the baselines in East-North-Up coordinates. Otherwise, plot in uv-space.

Return type:

None

argosim.plot_utils.plot_beam(beam, pRng=(-0.1, 0.5), ax=None, fig=None)[source]#

Plot beam.

Function to plot the synthesised beam image.

Parameters:

  • beam (np.ndarray) – The beam image.

  • pRng (tuple) – The range of the colorbar.

  • ax (matplotlib.axes.Axes) – The axis to plot the beam. For plotting on a specific subplot axis.

  • fig (matplotlib.figure.Figure) – The figure to plot the beam. For plotting on a specific subplot axis.

Return type:

None

argosim.plot_utils.plot_beam_fit(beam, fit_result=None)[source]#

Plot beam fit.

Plot the beam and overlay the fitted ellipse.

Parameters:

  • beam (np.ndarray) – 2D beam image.

  • fit_result (dict) – Dictionary containing the ellipse parameters (center, width, height, angle_deg, eccentricity). If None, it is computed from the beam.

Return type:

None

argosim.plot_utils.plot_sky(image, fov_size=(1.0, 1.0), ax=None, fig=None, title='Sky')[source]#

Plot sky.

Function to plot the sky model.

Parameters:

  • image (np.ndarray) – The sky model image.

  • fov_size (tuple) – The field of view size in degrees.

Return type:

None

argosim.plot_utils.plot_sky_uv(sky_uv, fov_size)[source]#

Plot sky uv.

Function to plot the sky model in uv-space in logarithmic amplitud sale.

Parameters:

sky_uv (np.ndarray) – The sky model in uv-space.The inverse fourier transform of the sky model.

Return type:

None

argosim.plot_utils.plot_uv_hist(baselines, bins=20, output_folder=None)[source]#

Plot uv histogram.

Function to plot the histogram of the uv-sampling distribution.

Parameters:

  • baselines (np.ndarray) – The uv-space sampling positions.

  • bins (int) – The number of bins for the histogram.

  • output_folder (str) – The output folder to save the plot.

Returns:

The histogram of the uv-sampling distribution.

Return type:

np.ndarray
