noise_maps

class txpipe.noise_maps.TXExternalLensNoiseMaps(*args: Any, **kwargs: Any)

Bases: ceci.

accumulate_maps(pixel_scheme, data, mappers)

Subclasses must override to supply the next chunk “data” to their mappers

choose_pixel_scheme()

Subclasses can override to instead load pixelization from an existing map

data_iterator()

Subclasses must override to create an iterator looping over input data

finalize_mappers(pixel_scheme, mappers)

Subclasses must override to finalize their maps and return a dictionary of (output_tag, map_name) -> (pixels, values)

prepare_mappers(pixel_scheme)

Subclasses must override to init any mapper objects

class txpipe.noise_maps.TXNoiseMaps(*args: Any, **kwargs: Any)

Bases: ceci.

Generate a suite of random noise maps by randomly rotating individual galaxy measurements.

Only works if the source and lens catalogs are the same lengths. Otherwise use TXSourceNoiseMaps and TXLensNoiseMaps below
