-We use `python-casacore <https://casacore.github.io/python-casacore/index.html>`_ to compute the direction of a given pointing with respect to our antennas and reference positions. Casacore in turn uses *measures* tables for the precise measurements of celestial positions, geodetical information, and time calibrations (f.e. leap seconds). These tables need to be installed and periodically updated to maintain the pointing accuracy:
-
-:measures_directory_R: Directory of the active set of measures tables. The directory name includes the timestamp denoting their age.
-
-  :type: ``str``
-
-:measures_directories_available_R: List of installed sets of measures tables.
-
-  :type: ``str[64]``
-
-:download_measures(): Download (but do not activate) the latest measures tables from ftp://ftp.astron.nl. Returns the directory name in which the measures were installed.
-
-  :returns: ``str``
-
-:use_measures(dir): Activate the measures tables in the provided directory. This necessitates turning off and restarting the TileBeam device, so the command will always appear to fail. Turn the device back and the selected measures tables will be active.

+The direction of each pointing is derived using *casacore*, which must be periodically calibrated, see also :ref:`casacore-measures`.
