Bases: BaseSurvey

Base Gravity Survey

Parameters:

source_fieldsimpeg.potential_fields.gravity.sources.SourceField

A source object that defines receivers locations for gravity.

Attributes

Qfx	Projection matrix from x-faces to receiver locations.
Qfy	Projection matrix from y-faces to receiver locations.
Qfz	Projection matrix from z-faces to receiver locations.
components	Number of components measured at each receiver.
counter	A SimPEG counter object for counting iterations and operations
nD	Number of data for the survey.
nRx	Returns the number of receivers in the survey
nSrc	Number of Sources
receiver_locations	Receiver locations.
source_field	A source object that contains the gravity receivers.
source_list	List of sources associated with the survey
uid	Universal unique identifier
vnD	Vector number of data

Methods

eval(fields)	Evaluate the field
get_all_slices()	Get slices to index a flat array for all source-receiver pairs.
get_slice(source, receiver)	Get slice to index a flat array for a given source-receiver pair.
get_source_indices(sources)
projectFields(u)	Project the fields from the mesh to the receiver locations.
