◆ _getMetadata()

PropertyList lsst.meas.algorithms.brightStarStamps.BrightStarStamp._getMetadata ( self )

protectedinherited

Extract metadata from the stamp's attributes.

This method constructs a `PropertyList` containing metadata
extracted from the stamp's attributes. It is used when writing the
stamp to a FITS file to store relevant metadata in the FITS headers.

Returns
-------
metadata : `PropertyList`
    A `PropertyList` containing the metadata, or `None` if no
    metadata attributes are defined.

Definition at line 163 of file brightStarStamps.py.

◆ factory()

BrightStarStamp lsst.meas.algorithms.brightStarStamps.BrightStarStamp.factory	(		cls,
		MaskedImageF	stamp_im,
		Psf \| None	psf,
		SkyWcs \| None	wcs,
		PropertyList	metadata )

inherited

Construct a `BrightStarStamp` from image data and metadata.

This method provides a standard interface to create a `BrightStarStamp`
from its image data, PSF, WCS, and associated metadata.
It is used by the `BrightStarStamps.readFits` method to construct
individual bright star stamps from FITS files.

Parameters
----------
stamp_im : `~lsst.afw.image.MaskedImageF`
    Masked image for the stamp.
psf : `~lsst.afw.detection.Psf`, optional
    Point-spread function for the stamp.
wcs : `~lsst.afw.geom.SkyWcs`, optional
    World coordinate system for the stamp.
metadata : `PropertyList`
    Metadata associated with the stamp, containing keys for all
    required attributes.

Returns
-------
brightStarStamp : `BrightStarStamp`
    The constructed `BrightStarStamp` instance.

Reimplemented from lsst.meas.algorithms.stamps.AbstractStamp.

Definition at line 194 of file brightStarStamps.py.

◆ metadata()

lsst.meas.algorithms.brightStarStamps.BrightStarStamps.metadata ( self )

Return the collection's global metadata as a PropertyList.

Reimplemented from lsst.meas.algorithms.brightStarStamps.BrightStarStamp.

Definition at line 274 of file brightStarStamps.py.

◆ readFits()

BrightStarStamps lsst.meas.algorithms.brightStarStamps.BrightStarStamps.readFits	(		cls,
		str	filename )

Make a `BrightStarStamps` object from a FITS file.

Parameters
----------
filename : `str`
    Name of the FITS file to read.

Returns
-------
brightStarStamps : `BrightStarStamps`
    The constructed `BrightStarStamps` instance.

Definition at line 279 of file brightStarStamps.py.

◆ readFitsWithOptions()

BrightStarStamps lsst.meas.algorithms.brightStarStamps.BrightStarStamps.readFitsWithOptions	(		cls,
		str	filename,
		PropertyList \| None	options )

Make a `BrightStarStamps` object from a FITS file, with options.

Parameters
----------
filename : `str`
    Name of the FITS file to read.
options : `~lsst.daf.base.PropertyList`, optional
    Options for reading the FITS file. Not currently used.

Returns
-------
brightStarStamps : `BrightStarStamps`
    The constructed `BrightStarStamps` instance.

Definition at line 295 of file brightStarStamps.py.

◆ writeFits()

lsst.meas.algorithms.brightStarStamps.BrightStarStamps.writeFits	(		self,
		str	filename )

Write this `BrightStarStamps` object to a FITS file.

Parameters
----------
filename : `str`
    Name of the FITS file to write.
