                         critical frequency (foF2), its peak height (hmF2), and the 
                         E-region critical frequency (foE) acquired during geomagnetically 
                         quiet days from September 2017 to August 2018. The monthly 
                         averages are compared to the 2016 version of the International 
                         Reference Ionosphere (IRI) model predictions in order to study its 
                         performance close to the center of the South America Magnetic 
                         Anomaly (SAMA), which is a region particularly important for 
                         high-frequency (HF) ground-to-satellite navigation signals. The

                         makes good predictions throughout the year, whereas, for hmF2, it 
                         is recommended to use the SHU-2015 option instead of the other 
                         available options (AMTB2013 and BSE-1979). The IRI-2016 model
