Dear all:

    I use anaddb code to calculate phonon of BN sheet. In the input file, I set eigvec=1, and the result contains many data block like this:

    Mode number    6   Energy    6.288962E-03
; 1 0.00000000E+00 5.35148649E-03 0.00000000E+00
;     0.00000000E+00 0.00000000E+00 0.00000000E+00
; 2 0.00000000E+00 -4.13050580E-03 0.00000000E+00
;     0.00000000E+00 0.00000000E+00 0.00000000E+00

   What's the unit of output eigvector? Is it in bohr? Another question, the direction of eigvectors go along a,b,c, not x,y,z, isn't it? In BN sheet, the angdeg= 90 90 120, along a,b,c and along x,y,z are not the same.
   Thanks!

Regards

                                                   Zhang Ting
