What is the measured bandpass stability or the expected bandpass stability for Early Science Cycle 0?

Authors list
The approximate bandpass stability for Early Science in Cycle 0 is about 0.5% at band 3, degrading to about 2% at band 7. The time variation for these changes are about one hour and is mostly caused by a membrane over the feeds. The variations are mostly a function of wind speed and direction.
