... Archives . ... Furthermore, numerical errors also creep in to the outputs based on how stopping rules are implemented: cases abound where repeated applications of the fitting program simply to move the ?best-fit? parameters closer to the true best-fit values but do not ever reach it. ... A typical strategy adopted to ensure that the fitting process does result in the best possible fit, is to ensure that the fitting process begins with parameters that are very close to the true best-fit values. ...
... The Iron Project seeks to provide new atomic data for all of the iron ions. ... For many of the ions in the CHIANTI database, energy level data has been taken from here. The CHIANTI database can be found within the SolarSoft system, a programming and data analysis environment for the solar physics community. A Package for Interactive Analysis of Line Emission written in IDL . ... This page contains some useful reviews for the analysis of emission lines and atomic data tables for several ions. ...
