Member Function Documentation

getPackedConfig()

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

Get a packed config suitable for using in a sha1.

Parameters
----------
config : `lsst.skymap.BaseTractBuilderConfig`

Returns
-------
configPacked : `bytes`

Reimplemented from lsst.skymap.tractBuilder.BaseTractBuilder.

Definition at line 255 of file tractBuilder.py.

getPatchBorder()

lsst.skymap.tractBuilder.BaseTractBuilder.getPatchBorder ( self )

inherited

Definition at line 96 of file tractBuilder.py.

getPatchIndexPair()

lsst.skymap.tractBuilder.BaseTractBuilder.getPatchIndexPair ( self, sequentialIndex )

inherited

Convert sequential index into patch index (x,y) pair.

Parameters
----------
sequentialIndex : `int`

Returns
-------
x, y : `lsst.skymap.Index2D`

Definition at line 167 of file tractBuilder.py.

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.

Reimplemented from lsst.skymap.tractBuilder.BaseTractBuilder.

Definition at line 223 of file tractBuilder.py.

getPatchInnerDimensions()

lsst.skymap.tractBuilder.BaseTractBuilder.getPatchInnerDimensions ( self )

inherited

Get dimensions of inner region of the patches (all are the same)

Definition at line 124 of file tractBuilder.py.

getSequentialPatchIndex()

lsst.skymap.tractBuilder.BaseTractBuilder.getSequentialPatchIndex ( self, patchInfo )

inherited

Return a single integer that uniquely identifies
the given patch within this tract.

Parameters
----------
patchInfo : `lsst.skymap.PatchInfo`

Returns
-------
sequentialIndex : `int`

Definition at line 129 of file tractBuilder.py.

getSequentialPatchIndexFromPair()

lsst.skymap.tractBuilder.BaseTractBuilder.getSequentialPatchIndexFromPair ( self, index )

inherited

Return a single integer that uniquely identifies
the patch index within the tract.

Parameters
----------
index : `lsst.skymap.Index2D` or `~collections.abc.Iterable` of 2 `int`

Returns
-------
sequentialIndex : `int`

Definition at line 144 of file tractBuilder.py.

setupPatches()

lsst.skymap.tractBuilder.BaseTractBuilder.setupPatches ( self, minBBox, wcs )

inherited

Set up the patches of a particular size in a tract.

We grow the tract bounding box to hold an exact multiple of
the desired size (patchInnerDimensions or
numCellsPerPatchInner*cellInnerDimensions), while keeping
the center roughly the same.  We return the final tract
bounding box, and the number of patches in each dimension
(as an Index2D).

Parameters
----------
minBBox : `lsst.geom.Box2I`
    Minimum bounding box for tract.
wcs : `lsst.afw.geom.SkyWcs`
    Wcs object.

Returns
-------
bbox : `lsst.geom.Box2I`
    final bounding box, number of patches.
numPatches : `lsst.skymap.Index2D`
