MulensModel.b0b1utils module

class MulensModel.b0b1utils.B0B1Utils

Bases: object

Data and methods used for interpolation for finite-source point-lens magnification calculations.

There are no parameters of __init__(). In general, this class is not directly used by a user.

interpolate_B0(z)

Interpolate B_0(z) function.

Parameters :

z: np.ndarray

Values of u/rho.

Returns :

B0: np.ndarray

Values of B_0.

interpolate_B0minusB1(z)

Interpolate B_0(z)-B_1(z) function.

Parameters :

z: np.ndarray

Values of u/rho.

Returns :

B0_minus_B1: np.ndarray

Values of B_0(z)-B_1(z).

interpolate_B1(z)

Interpolate B_1(z) function.

Parameters :

z: np.ndarray

Values of u/rho.

Returns :

B1: np.ndarray

Values of B_1(z).

interpolate_B0prime(z)

Interpolate derivative of B_0(z), i.e., d B_0(z)/d z.

Parameters :

z: np.ndarray

Values of u/rho.

Returns :

dB0_dz: np.ndarray

Values of d B_0(z)/d z.

interpolate_B1prime(z)

Interpolate derivative of B_1(z), i.e., d B_1(z)/d z.

Parameters :

z: np.ndarray

Values of u/rho.

Returns :

dB1_dz: np.ndarray

Values of d B_1(z)/d z.

get_interpolation_mask(z)

Get mask of z values for which interpolation of B_0(z), B_1(z) etc. is allowed

Parameters :

z: np.ndarray

Values of u/rho.

Returns :

mask: np.ndarray

Mask indicating for which z values interpolation is allowed.

property z_max_interpolation

Maximum value of z for which interpolation is allowed.
