) |
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.
