Rx EVM with interferer dependence on bandwidth

In AD9364 datasheet, I am referring to figs 35,36.

First, I wanted to clarify about the reference vector used in EVM definition. In these figures, the reference vector would mean the input signal power and not the blocker power, is that right?

In our application, the interferer is located at greater than 80MHz from the signal. Is there any data for Rx EVM for offsets greater than 40 MHz (as used in fig 36).

Lastly, what are the typical sources in the receiver section which contribute to Rx EVM in presence of blocker? Can you provide any insights into this, which can help us to determine the Rx EVM impairment in our specific application?
