Define a sampling grid for use as input to SHORT_MODEL. The sampling
grid is a regular rectangular grid large enough to cover the size of the
input sky image. It is better than Nyquist sampled, i.e. the pixel size
is the beam width divided by POINT_PER_BEAM$. One grid point either pass
through the sky image center or the reference pixel available in the sky
To better mimic On-The-Fly observations the grid should have Nyquist
sampling perpendicular to the scanning direction.
The grid nod positions are given in radian as offsets compared to the
reference position of the sky image. The grid is duplicated by the num-
ber of Single-Dish antenna simultaneously observing. The output table
has the following format: Number of position x Number of antenna x 2
(Lambda and Beta coordinates).
