Read stamps from FITS file, allowing for only a subregion of the stamps to be read. Parameters ---------- filename : `str` A string indicating the file to read stamp_factory : classmethod A factory function defined on a dataclass for constructing stamp objects a la `lsst.meas.alrogithm.Stamp` options : `PropertyList` or `dict` A collection of parameters. If it contains a bounding box (``bbox`` key), or if certain other keys (``llcX``, ``llcY``, ``width``, ``height``) are available for one to be constructed, the bounding box is passed to the ``FitsReader`` in order to return a sub-image. Returns ------- stamps : `list` of dataclass objects like `Stamp`, PropertyList A tuple of a list of `Stamp`-like objects metadata : `PropertyList` The metadata

) |
Write a single FITS file containing all stamps. Parameters ---------- filename : `str` A string indicating the output filename stamps_ims : iterable of `lsst.afw.image.MaskedImageF` An iterable of masked images metadata : `PropertyList` A collection of key, value metadata pairs to be written to the primary header type_name : `str` Python type name of the StampsBase subclass to use write_mask : `bool` Write the mask data to the output file? write_variance : `bool` Write the variance data to the output file?
