`Time`	Name of the sampling time variable.
`Data`	Name of the measured variable.
`Type`	either “frequency” or “period”.
`Oversampling factor`	The degee of oversampling (>=1).
`From`	The lowest frequency (or period, depending on type) inspected.
`To`	The highest frequency (or period, depending on type) inspected.
`# frequencies`	The number of frequencies (or periods, depending on type) inspected.
`PNmax`	The peak normalised power in the periodogram.
`At frequency`	The frequency at which PNmax occurred.
`At period`	The period at which PNmax occurred.
`P-value (PNmax)`	The probability that PNmax occured by chance, computed from the exponential distribution.
