getPackedConfig()

lsst.skymap.tractBuilder.LegacyTractBuilder.getPackedConfig	(		self,
			config )

Get a packed config suitable for using in a sha1.

Parameters

getPatchInfo()

lsst.skymap.tractBuilder.LegacyTractBuilder.getPatchInfo	(		self,
			index,
			tractWcs )

Return information for the specified patch.

Parameters
----------
index : `lsst.skymap.Index2D` or `~collections.abc.Iterable` of 2 `int`
    Index of patch, as Index2D or pair of ints;
    or a sequential index as returned by getSequentialPatchIndex;
    negative values are not supported.
tractWcs : `lsst.afw.geom.SkyWcs`
    WCS associated with the tract.

Returns
-------
result : `lsst.skymap.PatchInfo`
    The patch info for that index.

Raises
------
IndexError
    Raised if index is out of range.
