A Principle Component Analysis of Galaxy Properties from a Large, Gas-Selected Sample

Figure 5

Scatter plots showing correlations between eight measured variables, including 2MASS data and reducing to 479 galaxies. All the variables are in solar units and with logarithmic representation. The diagonal line is the histograms, which have vertical scales from 0 to 350. There are small numbers of outliers in many of the plots. They are likely misidentifications or bad photometry, and they do not impact our analyses.
