   $^a$ Because of the strong nebular emission in this object, all regions but the companion object have been corrected using these values;
   $^b$ these values have been also used to correct the colors of SBS 1211+540 integrating all its flux;
   $^c$ all objects (Obj~1, B, C, d, Obj 2, e, f and g) except region~A.
