Bases:
AbstractStamp
Single stamp
- Parameters:
- stamp_im

Methods Documentation
- classmethod factory(stamp_im, metadata, index, archive_element=None)¶
This method is needed to service the FITS reader. We need a standard interface to construct objects like this. Parameters needed to construct this object are passed in via a metadata dictionary and then passed to the constructor of this class. If lists of values are passed with the following keys, they will be passed to the constructor, otherwise dummy values will be passed: RA_DEG, DEC_DEG. They should each point to lists of values.
- Parameters:
- stamp
lsst.afw.image.MaskedImage
Pixel data to pass to the constructor
- metadata
dict
Dictionary containing the information needed by the constructor.
- idx
int
Index into the lists in
metadata
- archive_element
afwTable.io.Persistable
, optional Archive element (e.g. Transform or WCS) associated with this stamp.
- stamp
- Returns:
- stamp
