Gaussian 03 Online Manual
This properties keyword tells Gaussian to compute electrostatic properties [276,278,377,555]. By default, the potential, electric field, and electric field gradient at each nucleus are computed. The density used for the electrostatic analysis is controlled by the Density keyword.

INPUT SOURCE-RELATED OPTIONS
If both Read and Opt are specified, the order of the input sections is fixed points (Read), then optimized points (Opt).
Three additional input lines are required for a uniform grid:
KTape,XO,YO,ZO Fortran unit for write, coords. of map's lower left corner. N1,X1,Y1,Z1 # grid rows & vertical step size. N2,X2,Y2,Z2 # grid column & horizontal step size.
For points read from an auxiliary file, a single line of input supplies all of the necessary information:
The coordinates of N points in Angstroms will be read from unit LTape, in format 3F20.12. LTape defaults to 52. The potential (NEFG=3), potential and field (NEFG=2), or potential, field, and field gradient (NEFG=1) will be computed and written to unit KTape. For example, the following input indicates that 19,696 points for the electrostatic potential (code 3) will be read from Fortran unit 10, with output written to Fortran unit 11:
HF, all DFT methods, CIS, MP2, MP3, MP4(SDQ), CID, CISD, CCD, CCSD and QCISD.
