Difference between the flux values measured by our survey and those found in the literature. For comparison purposes, the previously published measurements are broken into two categories - previous Arecibo measurements (black diamonds) and previous measurements made at other telescopes (blue squares). The weighted average for the samples are shown as solid lines (and lie at 0.0) while the unweighted medians for the two samples are shown as dashed lines.
