Plots of all the pair combinations between the cloud properties to show how they correlate. Each point in each plot represents one of the 337 clouds in the sample. For each plot, the x-axis corresponds to the parameter on the diagonal for the same column and the y-axis to the parameter on the diagonal for the same line. For example, the plot in the eighth column and fifth row shows the cloud mass as derived from the CO luminosity (“M_H2” – see Table A.1) as a function of the peak CO line temperature (“”) and the scales can be read at the top of the column for the x-axis and at the right end of the row for the y-axis. For odd columns and even row numbers, the scales are respectively to the bottom and left. The units for each quantity are given in Table A.1.
