+Observation Simulation
+----------------------
+
+In order to incorporate the instrumental effects into the simulated
+sky maps, the latest `SKA1-Low layout configuration`_ (released on
+2016 May 21) is employed to carry out the observation simulation.
+
+The `OSKAR`_ simulator is used to perform the interferometric
+observations.  The ``make-ska1low-model`` tool was writen to generate
+the *sky model* of the SKA1-Low for use by ``OSKAR``.
+The simulated *visibility data* are then imaged by utilizing the
+`WSClean`_ to generate the "observed" images.
+
+The scripts that help carry out the observation simulations can be
+found at `atoolbox/astro/oskar`_.
