Experimentalists: understood, say no more.

Theorists: ok, show me the Hamiltonian...including the noise terms.

Sources of error: psychosomatic popping noise interfered with measurements when viewing image

Where was the experiment run? On a battlefield?

Setting up a bird listening device a few meters off an active runway and no filter for engine sounds.

Play back is of course volume tuned for the bird chirps when processing data

Hey boss, we have sincere troubles, SNR is off by too much.
how much?
20dB
