(a,b) Numerical impurity density asymmetry parameter <math>\alpha_{nZ}</math> and the
experimental radiation asymmetry parameter <math>\alpha_{rad}</math> respectively at the toroidal plane
<math>\phi=14.5^{\circ}</math> that corresponds the SXR toroidal measurement plane. (c,d) Numerical
impurity density asymmetry parameter <math>\alpha_{nZ}</math> and the experimental radiation asymmetry
parameter <math>\alpha_{rad}</math> respectively at the toroidal plane <math>\phi=75.5^{\circ}</math> that corresponds
the Bolometery toroidal position. Note the numerical and experimental scale sare
the same <math>[-0.38, 0.38]</math>. Since neon impurities were puffed at trave levels during the discharges, the numerical
results in (a,c) have considered <math>Z_{I}=10</math>, i.e. they have assumed fully ionization of Ne on the whole
