Question regarding tip convolution

I am using tapping mode and a RTESPA probe to measure the surface topography of a nanoparticle film. The film consists of spherical nanoparticles that measure roughly 50 nm in diameter in the AFM image. Is this particle diameter accurate? Since the particle is significantly larger than the tip radius of 5 nm, I would expect error due to convolution

ScanAsyst in Air Question

I am using a Dimension Icon with NanoScope v8.15 to image multiple locations on very similar samples. In ScanAsyst mode (with auto setpoint and auto z limit set to OFF) when I withdraw to move the stage and then reengage, the peak force setpoint and z range reset to default values. Is there any way to lock these values during a withdraw/reengage cycle
