Python API reference

lsst.cell_coadds Package

Functions

writeMultipleCellCoaddAsFits(...[, ...])

Write a MultipleCellCoadd object to a FITS file.

Classes

CellCoaddFitsFormatter(fileDescriptor, dataId)

Interface for writing and reading cell coadds to/from FITS files.

CellCoaddFitsReader(filename)

A reader class to read from a FITS file and produce cell-based coadds.

CellIdentifiers(skymap, tract, patch, band, cell)

Struct of identifiers for a coadd cell.

CoaddUnits(value[, names, module, qualname, ...])

Enumeration of units a coadd's pixels may have.

CommonComponents(units, wcs, band, identifiers)

Struct containing image attributes that are common to all cells in a patch.

CommonComponentsProperties()

A mix-in class that provides properties for all common components to any derived class that provides a property for the common components struct itself.

ExplodedCoadd(cell_coadd, *[, pad_psfs_with])

A lazy-evaluation coadd that stitches together the outer regions of the cells in a MultipleCellCoadd (including multiple values for most pixels).

GridContainer(shape[, offset])

A container whose elements form a 2-d grid.

ImagePlanes()

Struct interface for the image-like planes we coadd.

MultipleCellCoadd(cells, grid, ...[, inner_bbox])

A data structure for coadds built from many overlapping cells.

MultipleCellCoaddBuilderConfig(*args, **kw)

Configuration parameters for the MultipleCellCoaddBuilderTask.

MultipleCellCoaddBuilderConnections(*[, config])

MultipleCellCoaddBuilderTask(**kwargs)

Task to build cell-based coadded images.

ObservationIdentifiers(instrument, ...)

Struct of identifiers for an observation that contributed to a coadd cell.

OwnedImagePlanes(*, image, mask, variance[, ...])

An implementation of the ImagePlanes interface backed by actual afw objects.

PatchIdentifiers(skymap, tract, patch, band)

Struct of identifiers for a coadd patch.

SingleCellCoadd(outer, *, psf, inner_bbox, ...)

A single coadd cell, built only from input images that completely overlap that cell.

SingleCellCoaddBuilderConfig(*args, **kw)

Configuration for a single-cell coadd builder.

SingleCellCoaddBuilderTask([config, name, ...])

An abstract interface for tasks building coadds in cells.

StitchedCoadd(cell_coadd, *[, bbox])

A lazy-evaluation coadd that stitches together images from adjacent cells.

StitchedImagePlanes()

An ImagePlanes intermediate base class that stitches together per-cell images.

StitchedPsf(images, grid)

A piecewise PSF implementation backed by a 2-d grid of images.

UniformGrid(cell_size, shape, *[, padding, min])

A 2-dimensional integer grid.

ViewImagePlanes(target, make_view[, bbox])

An implementation of the ImagePlanes interface that extracts views from another target ImagePlanes instance.
