\section{Pointing Time}  The second factor of the time of observation is the pointing time. A restriction on this is that there must be enough pointings to cover the area that we wish to cover. So, our image which is ~ 2' to a side requires ~ 30 pointings. Therefore,   Total_time >= 30 Integration time  The suggested time for real observations is \href{http://casaguides.nrao.edu/index.php?title=Simulation_Guide_for_New_Users_(CASA_3.4)}{10s}. In general, shorter pointings are better but add overhead (read out, changing pointing) to the time required.   We shall investigate the difference between 10 and 30 pointings.
