Descripción
A detailed NLTE investigation of Fe I lines is carried out for the MACKKL quiet solar atmospheric model using a very realistic iron atomic model. This improved atomic model consists of about 250 multiplets and nearly 500 UV, optical and IR bound-bound and bound-free transitions including the regime near the Fe I continuum. The authors find and discuss some interesting statistical regularities with respect to the errors found for the heights of formation, source functions, equivalent widths and the central depths of the Fe I lines when the LTE approximation is adopted.
