The data in labeled density_DFT_* can be used to test the output of the provided DFT script when LDA and SCAN are used with a different number of bands [180 and 280] at the perturbation amplitude  A=0.1. The information about simulation parameters is stored in the info_*.txt files. The labels q1 (q3) denote the perturbation wave number q=q_min (q=3q_min). See the associated paper for more details. 
Additional DFT results for different values A, q, and N and for different XC functionals are available upon request via email z.moldabekov@hzdr.de.
