lib.survey_selection.base.ProjectionConversion

class lib.survey_selection.base.ProjectionConversion(x, projsin, projsout=None)

Bases: lib.survey_selection.base.BaseRegularMatrix

Class that handles conversion between different projection bases.

projmatrix

Array of shape (len(self.projsout),len(self.projsin)) to convert input array from one basis to another (e.g. multipoles to wedges).

Type

array

Initialize ProjectionConversion.

Parameters

• x (array) – x-coordinates, same for each input and output projections.

• projsin (list, ProjectionNameCollection) – Input projections.

• projsout (list, ProjectionNameCollection, default=None) – Output projections. Defaults to projsin.

Methods

compute	Apply transform to input array.
copy	Return shallow copy of self.
deepcopy
from_state	Instantiate and initalize class with state dictionary.
is_mpi_broadcast
is_mpi_gathered
is_mpi_root
is_mpi_scattered
load	Load class in numpy binary format from disk.
load_auto	If different formats are possible, this method should between them based on file name extension.
log_critical
log_debug
log_error
log_info
log_warning
propose_out	Propose output projection names given proposed input projection names projsin.
save	Save class to disk.
save_auto	If different formats are possible, this method should between them based on file name extension.

Attributes

basis
logger
matrix	Return 2D array of shape (len(self.projsout)*len(self.x),len(self.projsin)*len(self.x)) corresponding to projmatrix.
mpiattrs	MPI attributes
mpicomm
mpiroot
mpistate
regularin
regularout
xin	Input x-coordinates.
xout	Output x-coordinates.

compute(array)

Apply transform to input array.

copy()

Return shallow copy of self.

classmethod from_state(state, mpiroot=0, mpicomm=None)

Instantiate and initalize class with state dictionary.

classmethod load(filename, mpiroot=0, mpicomm=None)

Load class in numpy binary format from disk. If the loaded state contains __class__ and that exists in cls._registry, return instance of cls._registry[__class__] (instead of cls).

load_auto(*args, **kwargs)

If different formats are possible, this method should between them based on file name extension.

property matrix

Return 2D array of shape (len(self.projsout)*len(self.x),len(self.projsin)*len(self.x)) corresponding to projmatrix.

property mpiattrs

MPI attributes

classmethod propose_out(projsin, baseout)

Propose output projection names given proposed input projection names projsin.

Parameters

• projsin (list, ProjectionNameCollection) – Input projections.

• baseout (ProjectionBasis) – Projection basis for output.

Returns

toret – Proposed projection names.

Return type

ProjectionNameCollection

save(filename)

Save class to disk.

save_auto(*args, **kwargs)

If different formats are possible, this method should between them based on file name extension.

property xin

Input x-coordinates.

property xout

Output x-coordinates.
