Magnetic structure of a perfect triangular
lattice at relatively low fields is numerically calculated
by superposing isolated flux lines based on the
Ginzburg-Landau theory. It is found that the magnetic flux
density is fairly uniform spatially and the difference
between the maximum and minimum values is
25~\% when the fluxoid spacing, $a_{\rm f}$, is equal
to the penetration depth, $\lambda$, and the G-L parameter
$\kappa=50$. The obtained magnetic structure is expressed
in the Fourier series and the expansion summed terms are
obtained as a function of $\kappa$ and $a_{\rm
f}/\lambda$. It is seen that the number of coefficients
needed for reconstruction becomes small with increasing
magnetic flux density.
