Top left: projected clustering relative to clustering of BOSS CMASS galaxies ordered by i-band absolute magnitude. The shaded region indicates the typical error of the clustering measurement. The red symbols indicate the clustering when BOSS galaxies are rank-ordered by the PCA masses. The yellow triangles indicate clustering when ranked by i-band absolute magnitude k-corrected to z = 0.52. The blue dotted curves are the clustering when ranked by Granada Granada masses. The green dashed curves indicate the clustering ranked by Portsmouth masses. The orange symbols indicate clustering when galaxies are ranked by velocity dispersion; orange circles are the PCA estimate of velocity dispersion, while orange squares are the Portsmouth dispersion estimate. All samples are the top 100,000 out of 350,000 galaxies in this redshift slice. Top right: projected clustering for a subset of the samples in the left panel (to avoid confusion). In this panel, clustering for the top 25,000 galaxies is measured for each rank-order. Red squares show the PCA masses with BC03 SPS models. The blue dotted curve is the fiducial Granada mass: early formation times, Kroupa IMF, dust modeling. The green dashed line is the fiducial Portsmouth mass, which uses Kroupa IMF. The yellow triangles represent k-corrected i-magnitude. The differences between PCA and other ranking methods is large enough to be seen without taking ratios.
