density

variable_vs_density(x, y, dx, x_param, y_param, param, box_size[, z=None, z_param=None, mode='2D', get_density=False])

Finds the relationship between a variable and the density of points.

Parameters:

• x (array) – Cartesian coordinates.

• y (array) – Cartesian coordinates.

• z (array) – Cartesian coordinates.

• x_param (array) – The positions associated with the measured parameter.

• y_param (array) – The positions associated with the measured parameter.

• z_param (array) – The positions associated with the measured parameter.

• param (array) – An array of the input parameter.

• dx (float) – The size of each cell in each axis.

• box_size (float) – The size of the box along one axis.

• mode (str) – ‘2D’ or ‘3D’.

• get_density (bool) – If true will output the density of particles.

Returns:

Returns a tuple of the following:

• mean_param (array) – The mean of the parameter in each cell.

• density (array) – The density of points in each cell.
