_pixels_to_radec()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask._pixels_to_radec ( self, wcs, pixels )

protected

Convert pixels to ra/dec positions using a wcs.

Parameters
----------
wcs : `lsst.afw.geom.SkyWcs`
    WCS object.
pixels : `list` [`lsst.geom.Point2D`]
    List of pixels to convert.

Returns
-------
radec : `numpy.ndarray`
    Nx2 array of ra/dec positions associated with pixels.

Definition at line 431 of file healSparseMapping.py.

add_warp_to_cell_input_map()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask.add_warp_to_cell_input_map	(		self,
			ccd_row,
			weight,
			cell )

Add a warp to the input map for a given cell.

Parameters
----------
ccd_row : `lsst.afw.table.ExposureRecord`
    Row from the ccd table.
weight : `float`
    Weight to use for this detector.
cell : `lsst.skymap.cellInfo.CellInfo`
    Cell that overlaps the ccd_table_row.

Definition at line 378 of file healSparseMapping.py.

build_ccd_input_map()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask.build_ccd_input_map	(		self,
			bbox,
			wcs,
			ccds )

Build a map from ccd valid polygons or bounding boxes.

Parameters
----------
bbox : `lsst.geom.Box2I`
    Bounding box for region to build input map.
wcs : `lsst.afw.geom.SkyWcs`
    WCS object for region to build input map.
ccds : `lsst.afw.table.ExposureCatalog`
    Exposure catalog with ccd data from coadd inputs.

Definition at line 145 of file healSparseMapping.py.

build_cell_input_map()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask.build_cell_input_map	(		self,
			cell )

Add a cell to the input map.

Parameters
----------
cell : `lsst.skymap.cellInfo.CellInfo`
    Cell to initialize.

Definition at line 360 of file healSparseMapping.py.

finalize_ccd_input_map_mask()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask.finalize_ccd_input_map_mask

(

self

)

Use accumulated mask information to finalize the masking of
ccd_input_map.

Raises
------
RuntimeError : Raised if build_ccd_input_map was not run first.

Definition at line 291 of file healSparseMapping.py.

initialize_cell_input_map()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask.initialize_cell_input_map	(		self,
			bbox,
			wcs,
			visit_detectors )

Initialize the cell input map.

Parameters
----------
bbox : `lsst.geom.Box2I`
    Bounding box for region to build input map.
wcs : `lsst.afw.geom.SkyWcs`
    WCS object for region to build input map.
visit_detectors : `list` [`tuple`]
    List of visit/detector tuples.

Definition at line 313 of file healSparseMapping.py.

mask_warp_bbox()

lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask.mask_warp_bbox	(		self,
			bbox,
			visit,
			mask,
			bit_mask_value )

Mask a subregion from a visit.
This must be run after build_ccd_input_map initializes
the overall map.

Parameters
----------
bbox : `lsst.geom.Box2I`
    Bounding box from region to mask.
visit : `int`
    Visit number corresponding to warp with mask.
mask : `lsst.afw.image.MaskX`
    Mask plane from warp exposure.
bit_mask_value : `int`
    Bit mask to check for bad pixels.

Raises
------
RuntimeError : Raised if build_ccd_input_map was not run first.
