◆ applyProperMotions()

def lsst.meas.algorithms.loadReferenceObjects.ReferenceObjectLoaderBase.applyProperMotions	(	self,
		catalog,
		epoch
	)

inherited

Apply proper motion correction to a reference catalog.

Adjust position and position error in the ``catalog``
for proper motion to the specified ``epoch``,
modifying the catalog in place.

Parameters
----------
catalog : `lsst.afw.table.SimpleCatalog`
    Catalog of positions, containing at least these fields:

    - Coordinates, retrieved by the table's coordinate key.
    - ``coord_raErr`` : Error in Right Ascension (rad).
    - ``coord_decErr`` : Error in Declination (rad).
    - ``pm_ra`` : Proper motion in Right Ascension (rad/yr,
        East positive)
    - ``pm_raErr`` : Error in ``pm_ra`` (rad/yr), optional.
    - ``pm_dec`` : Proper motion in Declination (rad/yr,
        North positive)
    - ``pm_decErr`` : Error in ``pm_dec`` (rad/yr), optional.
    - ``epoch`` : Mean epoch of object (an astropy.time.Time)
epoch : `astropy.time.Time`
    Epoch to which to correct proper motion.
    If None, do not apply PM corrections or raise if
    ``config.requireProperMotion`` is True.

Raises
------
RuntimeError
    Raised if ``config.requireProperMotion`` is set but we cannot
    apply the proper motion correction for some reason.

◆ joinMatchListWithCatalog()

def lsst.meas.algorithms.loadReferenceObjects.LoadReferenceObjectsTask.joinMatchListWithCatalog	(	self,
		matchCat,
		sourceCat
	)

Relink an unpersisted match list to sources and reference
objects.

A match list is persisted and unpersisted as a catalog of IDs
produced by afw.table.packMatches(), with match metadata
(as returned by the astrometry tasks) in the catalog's metadata
attribute. This method converts such a match catalog into a match
list, with links to source records and reference object records.

Parameters
----------
matchCat : `lsst.afw.table.BaseCatalog`
    Unperisted packed match list.
    ``matchCat.table.getMetadata()`` must contain match metadata,
    as returned by the astrometry tasks.
sourceCat : `lsst.afw.table.SourceCatalog`
    Source catalog. As a side effect, the catalog will be sorted
    by ID.

Returns
-------
matchList : `lsst.afw.table.ReferenceMatchVector`
    Match list.

Load reference objects that overlap a rectangular pixel region.

Parameters
----------
bbox : `lsst.geom.Box2I` or `lsst.geom.Box2D`
    Bounding box for pixels.
wcs : `lsst.afw.geom.SkyWcs`
    WCS; used to convert pixel positions to sky coordinates
    and vice-versa.
filterName : `str` or `None`, optional
    Name of filter, or `None` or `""` for the default filter.
    This is used for flux values in case we have flux limits
    (which are not yet implemented).
photoCalib : `None`
    Deprecated, only included for api compatibility.
epoch : `astropy.time.Time` or `None`, optional
    Epoch to which to correct proper motion and parallax, or `None` to
    not apply such corrections.

Returns
-------
results : `lsst.pipe.base.Struct`
    A Struct containing the following fields:
    refCat : `lsst.afw.catalog.SimpleCatalog`
        A catalog of reference objects with the standard
        schema, as documented in the main doc string for
        `LoadReferenceObjects`.
        The catalog is guaranteed to be contiguous.
    fluxField : `str`
        Name of flux field for specified `filterName`.

Notes
-----
The search algorithm works by searching in a region in sky
coordinates whose center is the center of the bbox and radius
is large enough to just include all 4 corners of the bbox.
Stars that lie outside the bbox are then trimmed from the list.

    If True then add field "variable".
coordErrDim : `int`
    Number of coord error fields; must be one of 0, 2, 3:

    - If 2 or 3: add fields "coord_raErr" and "coord_decErr".
    - If 3: also add field "coord_radecErr".
addProperMotion : `bool`
    If True add fields "epoch", "pm_ra", "pm_dec" and "pm_flag".

    Number of proper motion error fields; must be one of 0, 2, 3;

addParallax : `bool`
    If True add fields "epoch", "parallax", "parallaxErr"
    and "parallax_flag".

Returns
-------
schema : `lsst.afw.table.Schema`
    Schema for reference catalog, an
    `lsst.afw.table.SimpleCatalog`.

Notes
-----
Reference catalogs support additional covariances, such as
covariance between RA and proper motion in declination,
that are not supported by this method, but can be added after
calling this method.
