A few days ago I got some new modes that are zero mean. Since the first most is a column of 1's, this means that the other modes are orthogonal to mode 1 in the normal Euclidean sense, and also on the DM surface (theoretically). There's one less degree of freedom, so there are a total of 30 of these.
Its not clear yet if this is going to make a difference since they look pretty similar to the modes I was using before, but you never know. The most significant difference so far seems to be the norm of the phase shapes they reproduce. Maybe there's something that could be done with this parameter to scale them relative to the power in each mode of the disturbance.
Saturation is still a problem I'll have to live with, even though I tried scaling down the amplitude of the disturbance WF. In the mean time I'd like to compare the performance of the two sets of modes, obviously using a set of disturbances that don't cause saturation.
