Real data are always buried in noise, therefore to finalize a simulation of real data (for example, to test our observational algorithms) it is essential to add noise to the mock profiles created with MakeProfiles, see MakeProfiles. Below, the general principles and concepts to help understand how noise is quantified is discussed. MakeNoise options and argument are then discussed in Invoking MakeNoise.
