Unless otherwise noted, the format is lambda_0 in column 1, Omega_0 in
column 2 and the likelihood value in column 3. Thus, plot column 3 as a
function of columns 1 and 2 to get a greyscale plot. Column four
contains numbers for making a `real' contour plot: plotting a contour at
X, where 0 < X < 1, will give you the smallest contour which
encloses X% of the probability density (i.e. the values from column 3 or
the grey scale).
Note that Fig. 4 is essentially the product of Figs. 1 and 2.
For the purposes of the plots, in all cases the normalisation is, of
course, arbitrary. (This allows the values to fall within the range of
single precision real variables on most machines.) Figs. 1 and 2 do
contain, however, the actual likelihood.
