Functions

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

Write a MultipleCellCoadd object to a FITS file.

Classes

CellCoaddFitsFormatter(file_descriptor, *, ref)	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.
IncompatibleVersionError	Exception raised when the CellCoaddFitsReader version is not compatible with the FITS file attempted to read.
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.
