This function adds the **standard tracking reconstruction** modules
to a path:
#. first we find tracks using the CDC hits only, see :ref:`CDC Track Finding<tracking_trackFindingCDC>`
#. CDC tracks are extrapolated to SVD and SVD hits are attached, see :ref:`CDC to SVD CKF<tracking_cdc2svd_ckf>`
#. remaining SVD hits are used to find SVD tracks, see :ref:`SVD Track Finding<tracking_trackFindingSVD>`
#. SVD tracks are extrapolated to CDC to attach CDC hits, see :ref:`SVD to CDC CKF<tracking_svd2cdc_ckf>`
#. SVD and CDC tracks are merged and fitted, see :ref:`Track Fitting<tracking_trackFitting>`
#. merged SVD+CDC tracks are extrapolated to PXD to attach PXD hits, see :ref:`SVD to PXD CKF<tracking_svd2pxd_ckf>`
.. note::
PXD hits are not available on HLT. At the end of the tracking chain on HLT we have the\
:ref:`PXD Region Of Interest Finding<tracking_pxdDataReduction>`, that consists of extrapolating\
the tracks on the PXD sensors and defining regions in which we expect to find the hit.\
Only fired pixels inside these regions reach Event Builder 2.
#. after all the tracks from the IP are found, we look for special classes of tracks,\
in particular we search for displaced vertices to reconstruct K-short, Lambda and\
photon-conversions, see :ref:`V0 Finding<tracking_v0Finding>`
.. note::
this last step is not run on HLT
