Counter
=======

count the number of flags per baseline, frequency, and correlation. A flagging step also counts how many visibilities it flagged. Counts can be saved to a table to be plotted later using function ``plotflags`` in python module ``lofar.dppp``.

inputs
******


.. _Counter.json#/inputs/type:

type
++++

:type: ``string``

:doc: Case-insensitive step type; must be 'counter' (or 'count'). Note that the type defaults to the step name, so if step name ``count`` is used, nothing more needs to be specified `.`


.. _Counter.json#/inputs/jsonfilename:

jsonfilename
++++++++++++

:type: ``string``

:default: ``FlagPercentagePerStation.JSON``

:doc: Filename for the JSON output `.`


.. _Counter.json#/inputs/path:

path
++++

:type: ``string``

:default: ``""``

:doc: The directory where to create the flag percentages table. If empty, the path of the input MS is used `.`


.. _Counter.json#/inputs/save:

save
++++

:type: ``bool``

:default: ``False``

:doc: If true, the flag percentages per frequency are saved to a table with extension ``.flagfreq`` and percentages per station to a table with extension ``.flagstat``. The basename of the table is the MS name (without extension) followed by the stepname and extension `.`


.. _Counter.json#/inputs/savetojson:

savetojson
++++++++++

:type: ``bool``

:default: ``False``

:doc: If true, the flag ratios per antenna are saved as a JSON file `.`


.. _Counter.json#/inputs/showfullyflagged:

showfullyflagged
++++++++++++++++

:type: ``bool``

:doc: If true, all fully flagged baselines are shown in the baseline selection format using their antenna indices (not names). For example: 0&1; 3&7 `.`

:default: ``False``


.. _Counter.json#/inputs/warnperc:

warnperc
++++++++

:type: ``double``

:default: ``0``

:doc: If > 0, print an extra message for each baseline or channel with a percentage flagged higher than this value. Such a message line can be easily grep-ed `.`
