The shaded purple region shows a graph of the mount’s periodic error or PEC table. The X-axis represents
the time for one revolution of the worm. The Y-axis shows the magnitude of the correction at a given
worm position. The red line shows the actual periodic error correction, in arcseconds that is applied over
one revolution of the worm.
