Recently, Hirose-san gave me the measured surface maps of the PR3, PR2, SR3, and SR2 mirrors.
Since there were no PSD calculations yet, I did these with a scilab program that I have written for this purpose.

The results can be seen in the picture that is attached, together with the PSD of the beam splitter as comparison.
Obviously, all PSDs are not so different from each other which might be a good sign.
