[3dem] Cs question

[Morgan, David Gene]

Hi,

For those of you who have used any of the image processing programs to refine the Cs value for your microscope, how does the refined value compare to what the manufacturers claim?

As I understand it, the manufacturers simply calculate a Cs value for each microscope/pole piece model.  I guess I have always assumed that those values are relatively accurate, but I don't really have any data to support that.  Nor am I certain what would constitute "relatively accurate."

Any thoughts would be appreciated.  Thanks.
