Measured OC (top panel) and SC (bottom panel) albedo values from Goldstone (dots) and GBT (crosses) plotted as a function of β angle. Each epoch is marked by a distinct color. For both telescopes and both polarizations, the albedo values remain approximately constant across the range of β values. However, within individual epochs, the GBT albedo values appear systematically lower than the corresponding Goldstone values, likely reflecting systematic biases in the telescope sensitivity estimates discussed earlier in this section.
