For example, SNR measurements made empirically align with theory only when these simulations are done using rms noise values. The rms noise value provides insight into image quality as well as being the appropriate noise variable in quantitative calculations. So when it comes to evaluating camera performance, the truly meaningful spec is rms noise. With sCMOS, the structure of the sensor inherently has more pixel variation, and the extreme low noise of the sensor makes variation more statistically significant. With CCDs there are never any issues regarding which model to use because the typical readout noise for all pixels is very similar, thus rms and median are equivalent. Median and rms are both perfectly valid statistical models, but only rms noise accurately represents the experience that a user can expect from a camera. This has always been the method used to calculate readout noise for CCDs. The classic electrical engineering method for calculating readout noise is to define the root mean square (rms). With any statistical parameter there are multiple models available to apply to the data.
