MOCPy is a Python library allowing easy creation and manipulation of MOCs (Multi-Order Coverage maps).
MOC is an IVOA standard enabling description of arbitrary sky regions. Based on the HEALPix sky tessellation, it maps regions on the sky into hierarchically grouped predefined cells.
A support for TMOC (temporal MOC) has been added since version 0.4.0. It allows creation, parsing and comparison of TMOCs. The support for Frequency MOCs has been added since version 0.13.0
Space & Time coverages (STMOC) are an extension of MOC to add time information. It is possible to get a TMOC by querying a STMOC with a MOC and/or get a MOC by querying a STMOC with a TMOC.
Please check the mocpy's documentation for more details about installing MOCPy and using it.
For a command line tool, see the moc-cli.
For more information about the MOCPy Rust core, see the moc crate.
