Main distances functions using catalogs.

clevar.match_metrics.distances.catalog_funcs.central_position(cat1, cat2, matching_type, radial_bins=20, radial_bin_units='degrees', cosmo=None, col2=None, bins2=None, **kwargs)[source]

Plot distance between central position of matched clusters, binned by a second quantity.

Parameters

  • cat1 (clevar.ClCatalog) – ClCatalogs with matching information.

  • cat2 (clevar.ClCatalog) – ClCatalogs with matching information.

  • matching_type (str) – Type of matching to be considered. Must be in: ‘cross’, ‘cat1’, ‘cat2’

  • radial_bins (array, int) – Bins for radial distances

  • radial_bin_units (str) – Units of radial bins

  • cosmo (clevar.Cosmology) – Cosmology (used if physical units required)

  • col2 (str) – Name of quantity 2 (of cat1) to bin

  • bins2 (array, int) – Bins for quantity 2

  • log2 (bool) – Log scale for quantity 2

  • mask1 (array, None) – Masks for clusters 1(2), must have size=cat1(2).size

  • mask2 (array, None) – Masks for clusters 1(2), must have size=cat1(2).size

  • shape (str) – Shape of the lines. Can be steps or line.

  • ax (matplotlib.axes) – Ax to add plot

  • plt_kwargs (dict, None) – Additional arguments for pylab.plot. It also includes the possibility of smoothening the line with n_increase, scheme arguments. See clevar.utils.smooth_line for details.

  • lines_kwargs_list (list, None) – List of additional arguments for plotting each line (using pylab.plot). Must have same size as len(bins2)-1

Returns

info –

Information of data in the plots, it contains the sections:

  • ax: ax used in the plot.

  • distances: values of distances.

  • data: Binned data used in the plot. It has the sections:

    • hist: Binned distances with (distance_bins, bin2). bins where no cluster was found have nan value.

    • distance_bins: The bin edges for distances.

    • bins2 (optional): The bin edges along the second dimension.

Return type

dict

Parameters
