ConfigClass = ConvertReferenceCatalogConfig | |
Class for producing HTM-indexed reference catalogs from external catalog data. This implements an indexing scheme based on hierarchical triangular mesh (HTM). The term index really means breaking the catalog into localized chunks called shards. In this case each shard contains the entries from the catalog in a single HTM trixel For producing catalogs this task makes the following assumptions about the input catalogs: - RA, Dec are in decimal degrees. - Epoch is available in a column, in a format supported by astropy.time.Time. - There are no off-diagonal covariance terms, such as covariance between RA and Dec, or between PM RA and PM Dec. Support for such covariance would have to be added to to the config, including consideration of the units in the input catalog. Parameters ---------- output_dir : `str` The path to write the output files to, in a subdirectory defined by ``DatasetConfig.ref_dataset_name``.

def lsst.meas.algorithms.convertReferenceCatalog.ConvertReferenceCatalogTask.makeSchema | ( | self, | |
dtype | |||
) |
Make the schema to use in constructing the persisted catalogs. Parameters ---------- dtype : `numpy.dtype` Data type describing each entry in ``config.extra_col_names`` for the catalogs being ingested. Returns ------- schemaAndKeyMap : `tuple` of (`lsst.afw.table.Schema`, `dict`) A tuple containing two items: - The schema for the output source catalog. - A map of catalog keys to use in filling the record

def lsst.meas.algorithms.convertReferenceCatalog.ConvertReferenceCatalogTask.run | ( | self, | |
inputFiles | |||
) |
Index a set of files comprising a reference catalog. Outputs are persisted in the butler repository. Parameters ---------- inputFiles : `list` A list of file paths to read.
