orca.wrapper.ttcal
==================

.. py:module:: orca.wrapper.ttcal

.. autoapi-nested-parse::

   TTCal peeling and calibration wrapper.

   Provides Python interface to TTCal, a Julia-based direction-dependent
   calibration tool for peeling bright sources from visibility data.
   Supports both standard peeling and polarized (ZEST) peeling modes.

.. py:data:: TTCAL_EXEC
   :value: '/opt/devel/pipeline/envs/julia060/bin/ttcal.jl'


.. py:function:: peel_with_ttcal(ms: str, sources: str)

   Use TTCal to peel sources.

   :param ms: Path to the measurement set.
   :param sources: Path to the sources.json file.

   Returns: The path to the measurement set because TTCal reads from and writes to it.


.. py:function:: zest_with_ttcal(ms: str, sources: str = '/yourdirectory/sources.json', beam: str = 'constant', minuvw: int = 10, maxiter: int = 30, tolerance: str = '1e-4')

   Use TTCal to run 'zest' with sensible defaults.

   :param ms: Path to the measurement set.
   :param sources: Path to the sources.json file (default: /yourdirectory/sources.json).
   :param beam: TTCal beam model (default: 'constant').
   :param minuvw: Minimum uvw in wavelengths (default: 10).
   :param maxiter: Maximum iterations (default: 30).
   :param tolerance: Solver tolerance (default: '1e-4').

   Returns: The path to the measurement set (TTCal reads/writes in-place).
