 Selecting the data for the object of interest will require entering the object coordinates in the "Spatial" constraints on the left, selecting the "Cone shape" button and a 2 arcseconds radius.  
 
 For the output column, selection of the ``midPointTai`` will yield the time of the observation, ``psFlux`` will give the flux, and ``filterName`` will provide the filter used for the observation.
+Pressing on the "funnel" icon will restrict the gtable on the right to show only the selected entries.

+The right-hand plot, by default, will plot the first two columns of the table.
+To plot the flux against time, it is necessary to click on the "gear" icon, and select the "midPointTai-60000" for X and "psFlux" for Y as shown below.

+Note that the resulting plot on the right-hand side displays flux in all filters.
+It is possible to restrict the flux from a single filter by clicking the down-arrow under the "filterName" column heading in the table on the bottom, and selecting only the desired filter, say "r".
