More work on implementing sCMOS analysis. This now touches the analysis routines that are also used for 3D-DAOSTORM. The shared (fitting) functions have been changed to include a sCMOS specific term. This is term is set to zero for 3D-DAOSTORM analysis so it should not have any effect. The other change is that we now explicity look for negative values in the fit and throw out the corresponding peaks. Since I did not think it necessary any more I removed the check for negative background values.
Update the windows 64 bit DLL to reflect the recent changes.
