 For the "Output Column Selection" only the ``diaObjectId`` and ``gPSFluxNdata`` need to be checked.
 (The ``gPSFluxNdata`` will return the number of observations in the ``g`` band, and if there are multiple objects in the search radius - the one with a larger mumber of data points needs to be selected.)

 The ``ForcedSourceOnDiaObject`` contains fluxes of individual objects, but it does not contain the observation epochs;  however, the table ``CcdVisit`` does.
 Obtaining the visit epochs will require joining two tables - specifically ``ForcedSourceOnDiaObject`` and ``CcdVisit`` on the common meta entry of ``ccdVisitId``.
