Optimum sPSD of \({\hat{F}}(\omega )\) normalized with the SQL as a function of scaled detection frequency \(\omega /\Omega \) (a) across the low frequency regime and (b) enlarged in the vicinity of the mechanical resonance. The parameters used are \(\kappa /\Omega = 10^2\) and \(\Gamma /\Omega = 10^{-3}\).
