 The ``calibFlux`` is the flux within a 12 pixel aperture; aperture fluxes are appropriate to use when calculating extended object colors.  
 It converts the fluxes to magnitudes, by the use of an ADQL function ``scisql_nanojanskyToAbMag`` where the respective flux is the argument (and renames them as ``gmag`` and ``rmag``).  
 It restricts the search to return only objects with g and i magnitudes less than 23.  
-It limits the search to those objects located in a circular region with a radius of 1 degree, around direction with RA of 55.75 deg and and Dec of -32.27 deg, via the restriction ``CONTAINS(POINT('ICRS', coord_ra, coord_dec), CIRCLE('ICRS', 55.75, -32.27, 1.0)) = 1 ``.
