The data gives the positions of the individual caveolae in a square region
with sides of length 500 units. This grid was originally on a 2.65mum
square of muscle fibre. The data are those points falling in the lower left
hand quarter of the region used for the
dataset caveolae.dat in the spatial library by B.D. Ripley (1994) which
is available from Statlib
