LDA(GGA)-1/2 program for Siesta

 *Please use Siesta 2.0.2 to generate *.ion file, in order to avoid charge divergence. Yet, the new *.ion files with self-energy correction can be used for Siesta 3.* and 4.* calculations.
 Element:    Strip - e  Power index
 Scan cutoff radii from bohr   to bohr
 Upload *.ion file and start the run:
