// //
-// If the querried point is outside the validity region no the return values //
-// for the field components are set to 0. //
+// Two options are possible: //
+// 1) _BRING_TO_BOUNDARY_ is defined in the AliCheb3D: //
+// If the querried point is outside of the validity region then the field //
+// at the closest point on the fitted surface is returned. //
+// 2) _BRING_TO_BOUNDARY_ is not defined in the AliCheb3D: //
+// If the querried point is outside of the validity region the return //
+// value for the field components are set to 0. //
// //
// To obtain the field integral in the TPC region from given point to nearest //
// cathod plane (+- 250 cm) use: //
// The units are kiloGauss and cm. //
