Hello,

what is the reason for negative deformation with QNM? The QNM calibration is done as careful as possible on clean sapphire. I`m analysing hard sample, and in 1 example, the deformation values has a gaussian distribution, with mean=0.18 nm and SD=0.72 nm, hence the distribution is centered close to zero, but values span on negative and positive values...

Thank you,

Andrea
