[CP2K-user] What exactly is SCALE of a COLVAR in METADYNAMICS?

[Itay Zackay]

Hello,

I understood that SCALE represents the width of the gaussians, but what 
exactly is meant by width? Is it the standard deviations, the variance, or 
the full width at half the maximum (FWHM)? or half the FWHM? Or something 
else?

I would be VERY thankful if someone could point on the width in the 
gaussian equation, so that I culd not be mistaken in understanding what 
exactly SCALE means?

Thanks a LOT

Itai
