Caption: Figure 10.

Relative throughput measures of amplifier LL versus wavelength for each spectrograph. Each panel presents data from a different set of spectrographs, where the spectrograph identification is given in the label near the top. The spectrographs with higher numbers are those installed at a later time and generally have higher relative throughput by about 10%. Each curve is based on the average of 112 fiber-to-fiber profiles within the amplifier. We use these curves to determine the relative throughput calibration over all IFUs.
