[Mne_analysis] Maxfilter and PCA-mag-v# projections

        External Email - Use Caution        

Dear MNE users,

can anyone enlighten me a little about the three 'default' projections 
PCA-mag-v1, PCA-mag-v2 and PCA-mag-v3. Where do they come from and why are they 
"discaded" by the maxfiltering process? My mags look pretty clean with them 
applied, but after maxfiltering, they look much worse, similar to not applying 
the PCA projections.

best,
Marijn.
