lsst.source.injection.generate_galsim_objects(injection_catalog: Table, photo_calib: PhotoCalib, wcs: SkyWcs, fits_alignment: str, stamp_prefix: str = '', logger: Any | None = None) → Generator[tuple[lsst.geom.SpherePoint, lsst.geom.Point2D, int, galsim.gsobject.GSObject], None, None]

Generate GalSim objects from an injection catalog.

Parameters:

injection_catalogastropy.table.Table

Table of sources to be injected.

photo_caliblsst.afw.image.PhotoCalib

Photometric calibration used to calibrate injected sources.

wcslsst.afw.geom.SkyWcs

WCS used to calibrate injected sources.

fits_alignmentstr

Alignment of the FITS image to the WCS. Allowed values: “wcs”, “pixel”.

stamp_prefixstr

Prefix to add to the stamp name.

loggerlsst.utils.logging.LsstLogAdapter, optional

Logger to use for logging messages.

Yields:

sky_coordslsst.geom.SpherePoint

RA/Dec coordinates of the source.

pixel_coordslsst.geom.Point2D

Pixel coordinates of the source.

draw_sizeint

Size of the stamp to draw.

objectgalsim.gsobject.GSObject

A fully specified and transformed GalSim object.
