pytomoatt.checkerboard

Module for generating checkerboard model.

class pytomoatt.checkerboard.Checker(fname: str)

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:

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

• period_y (float) – Multiple of period along Y

• period_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

• 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

init_axis(min_max_dep, min_max_lat, min_max_lon, n_rtp)

Parameters:

• min_max_dep (list) – min and max depth, [min_dep, max_dep]

• min_max_lat (list) – Min and max latitude, [min_lat, max_lat]

• min_max_lon (list) – Min and max longitude, [min_lon, max_lon]

• n_rtp (list) – number of dimensions [ndep, nlat, nlon]

write(fname)

Write new model to h5 file

Parameters:

fname (str) – Path to output file
