Calculate theoretical rms expected from current configuration. Used by RADIOM for comparison with empirical radiometer equation.
theoretical radiometer equation
rms := k1*tsys/sqrt(k2*teff*npol*df);where teff is the effective integration time given by
teff = ton*toff/(ton + toff)This code assumes ton equals toff hence
teff = tint / 2 ; tint is the integration time
