Hello,

I calculated the dipole derivative matrix of HF molecule at the HF/3-21G level. The matrix in *.fd_ddipole after edits is

         X          Y          Z
-0.4827 0.0000 0.0000
0.0000 -0.4827 0.0000
0.0000 0.0000 -0.1798
0.4827 0.0000 0.0000
0.0000 0.4827 0.0000
0.0000 0.0000 0.1798

which agrees with the result of other programs. However in the output file, the matrix (in a.u.) is

         X          Y          Z
-0.4445 0.0000 0.0000
0.0000 -0.4445 0.0000
0.0000 0.0000 -0.9156
0.4445 0.0000 0.0000
0.0000 0.4445 0.0000
0.0000 0.0000 0.9156

Is this a bug?
