Detailed Description

A cutout centered on a star, with associated metadata.

Parameters
----------
image : `~lsst.images.Image`
    The main data image for this star cutout.
mask : `~lsst.images.Mask`, optional
    Bitmask that annotates the main image's pixels.
variance : `~lsst.images.Image`, optional
    Per-pixel variance estimates for the image.
mask_schema : `~lsst.images.MaskSchema`, optional
    Schema for the mask, required if a mask is provided.
sky_projection : `~lsst.images.SkyProjection`, optional
    Projection to map pixels to the sky.
metadata : `dict` [`str`, `MetadataValue`], optional
    Additional metadata to associate with this cutout.
psf_kernel_image : `~lsst.images.Image`, optional
    Kernel image of the PSF at the cutout center.
star_info : `ExtendedPsfCandidateInfo`, optional
    Information about the star in the cutout.

Attributes
----------
psf_kernel_image : `~lsst.images.Image`
    Kernel image of the PSF at the cutout center.
star_info : `ExtendedPsfCandidateInfo`
    Information about the star in this cutout.
