calc_facTopo(site_name, grid_extent, grid3d_discr, grid3d_depth,
  topo_flat = F, pillar_correction = T, dir_input_DEM,
  DEM_fileType = "ascii")

`grid_extent`	vector, giving as first argument x and as second y grid extent in [m]
`grid3d_discr`	data.frame(x = 100, y = 100, z = 0.5)
`grid3d_depth`	c(-10, 0) # min, max
`dir_input`	directory of DEM file

Returns the topographic conversion factor which represents the gravity effect resulting from 1 mm of vertical water storage change. This factor is used to convert mm of water from precipitation or evapotranspiration measurements, etc. to gravity units [nm/s²].
