File name

  • Lanczos method: ##_cisajs.dat
  • TPQ method: ##_cisajs_set??step%%.dat
  • Full diagonalization method, LOBCG method: ##_cisajs_eigen&&.dat.
  • Real time evolution method: ## cisajs step%%.dat

##, ??, %%, and && indicate [string02] in a ModPara file, the number of runs in calculation in the TPQ method, the number of steps in the TPQ method, and the index of the eigenvalues, respectively.

File format
