First season results published

Third and final season right now coming to an end

Still fighting with contaminants
Ground pickup massively reduced by field difference technique
But does any remain?...
Moon pickup being exhaustively investigated...
Noise modelling may still not be good enough...
However, for EE residual contamination is already very small compared to sample variance
Ultimately the only practical impact likely to be slightly degraded limits on BB
