==========================

.. py:module:: orca.flagging.flag_bad_bls

.. autoapi-nested-parse::

   Baseline flagging based on cross-hand visibility statistics.

   Identifies bad baselines by analyzing cross-hand (XY, YX) correlation
   amplitudes. Baselines with excessive cross-hand power are flagged.

   Functions
   ---------
   flag_bad_bls
       Identify and write bad baselines to a text file.

.. py:function:: flag_bad_bls(msfile: str, usedatacol: bool = False) -> Optional[str]

   Flag bad baselines using the visibilities.

   Identifies baselines with anomalously high cross-hand (XY, YX) correlation
   amplitudes and writes them to a text file. Does NOT apply flags directly
   to the measurement set.

   :param msfile: Path to the measurement set.
   :param usedatacol: If True, use DATA column; otherwise use CORRECTED_DATA.

   :returns: Path to the text file listing baselines to flag, or None if no
             bad baselines were found. Format is one baseline per line as 'ant1&ant2'.
