SimPEG.potential_fields.magnetics.Point#

class SimPEG.potential_fields.magnetics.Point(locations, components='tmi', **kwargs)[source]#

Bases: BaseRx

Magnetic point receiver class for integral formulation

Parameters:

locations(n, 3) numpy.ndarray

Receiver locations.

componentsstr or list of str, default: ‘tmi’

Use a str for a single component or a list of str if multiple components are simulated at each location. Component choices are:

“tmi” –> total magnetic intensity data (DEFAULT)
“bx” –> x-component of the magnetic field
“by” –> y-component of the magnetic field
“bz” –> z-component of the magnetic field
“bxx” –> x-derivative of the x-component
“bxy” –> y-derivative of the x-component (and visa versa)
“bxz” –> z-derivative of the x-component (and visa versa)
“byy” –> y-derivative of the y-component
“byz” –> z-derivative of the y-component (and visa versa)
“bzz” –> z-derivative of the z-component
“tmi_x”–> x-derivative of the total magnetic intensity data
“tmi_y”–> y-derivative of the total magnetic intensity data
“tmi_z”–> z-derivative of the total magnetic intensity data

Notes

If predicting amplitude data, you must set include ‘bx’, ‘by’, and ‘bz’ here, and set is_amplitude_data in the magnetics.Simulation3DIntegral to True.
