cuperiod.uniform_frequency_grid

cuperiod.uniform_frequency_grid(baseline, *, maximum_frequency, minimum_frequency=None, samples_per_peak=5)

Build a uniform frequency grid, matching astropy autofrequency.

Parameters:

• baseline (float) – Time span max(t) - min(t) in days.

• maximum_frequency (float) – Highest trial frequency (cycles/day).

• minimum_frequency (float, optional) – Lowest trial frequency. Defaults to one Rayleigh step 1/(s*baseline).

• samples_per_peak (int, default 5) – Oversampling factor; the frequency step is 1/(samples_per_peak*baseline).

Returns:

GridSpec – A uniform frequency grid.

Return type:
