pytomoatt.checkerboard

Module for generating checkerboard model.

class pytomoatt.checkerboard.Checker(model_fname: str, para_fname='input_params.yml')

Bases: object

Create checkerboard model by adding perturbations on an exist model

checkerboard(n_pert_x: int, n_pert_y: int, n_pert_z: int, pert_vel=0.08, pert_ani=0.04, ani_dir=45, lim_x=None, lim_y=None, lim_z=None)

Create checkerboard

Parameters:

• n_pert_x (float) – Multiple of period along X, e.g., set to 1 for 2 anomalies

• n_pert_y (float) – Multiple of period along Y

• n_pert_z (float) – Multiple of period along Z

• pert_vel (float, optional) – Perturbation for velocity, defaults to 0.08

• pert_ani (float, optional) – Perturbation for anisotropy, defaults to 0.04

• ani_dir (float, optional) – Direction of fast velocity direction, defaults to 45

• lim_x (list, optional) – Left and right bound along X, defaults to None

• lim_y (list, optional) – Left and right bound along Y, defaults to None

• lim_z (list, optional) – Left and right bound along Z, defaults to None

copy()

Create a deep copy of the Checker object

Returns:

A copy of the Checker object

Return type:

Checker

write(fname)

Write new model to h5 file

Parameters:

fname (str) – Path to output file
