Goodness-of-fit pseudo-color map for derivative of POLE_RA and spin rate. The goodness-of-fit metric is E tot/N. The x-axis is spin rate. The y-axis is rate of change in pole right ascension. The color scale goes from dark blue = 1.2 km to dark red > 2.4 km. The X indicates the synchronous no-pole-wobble case. Due to correlation between the two parameters, the locus of good fits is elongated.
