dalcorso 7a3377305d A tentative to improve the paw pseudopotential generation and test.
Main changes:
The PAW file contains three new arrays (els, jjs, rcutus). Please
update the reader in pw to use these pseudopotentials.
The starting charge and wavefunctions are calculated from the all
electron wavefunctions of the current configuration.
The n1 and n1~ charges are set to zero outside the sphere before
computing energies and potentials.
The n1 and n1~ charges are set to zero when n~ becomes lower than
10^-11 before descreening the effective potentials.
The energy terms are exported to the ld1 variables and printed.
Bug fix: The product of the wavefunctions and the projectors is done
until ikk not irc.
Added two examples of generation and test (Cu and Si).

README

This is the distribution of the ld1 code for electronic structure 
atomic calculations and pseudo-potentials generation.

The ld1 code, maintained by Andrea Dal Corso (SISSA, Trieste) 
is the result of several additions to the original code by
P. Giannozzi (http://web1.sns.it/~giannozz/software.html) for 
pseudopotential generation. The major additions are:

a) Generation and test of norm-conserving and ultrasoft pseudo-potentials
   with the Rappe-Rabe-Kaxiras-Joannopoulos (RRKJ) recipe
   ( Phys. Rev. B41, 1227 (1990); Phys. Rev. B 44, 13175 (1991) )
b) Generation of fully relativistic pseudo-potentials including 
   spin-orbit coupling.

Input variables are described in file INPUT_LD1.
Directories all-electron/, pseudo-gen/, pseudo-test/, 
contain tests for the three modes of operation, respectively:
all-electron run, pseudo-potential generation, pseudo-potential testing.
