qspec.convolved_thermal_norm_f_lin_pdf  (  f ,  xi ,  sigma ,  col = True  )[source]

Parameters:

farray_like

Frequency quantiles (arb. units).

xiarray_like

The proportionality constant between kinetic energy differences and frequency differences ([f]).

sigmaarray_like

The standard deviation of the underlying normal distribution in frequency units ([f]).

colNone

Col/Acol alignment of the laser relative to the atom beam.

Returns:

outarray_like

The probability density at the frequency 'f' in the atoms rest frame, related to differences in kinetic energy via the proportionality constant 'xi'. The kinetic energies are distributed according to a convolution of the boltzmann and a normal distribution (1/[f]).
