Period range implied by the frequency resolution of a record

Usage

cycle_band(period, record_length = NULL, tol = NULL, mult = 1)

period: Measured period of the cycle (single numeric value, > 0): in kyr for a tuned record or in metres for a depth series. Required, no default.
record_length: Length of the analysed record, in the same unit as period (numeric, > 0; kyr for a tuned record, metres for a depth series). The half-width of the band is mult / record_length in frequency (the Rayleigh resolution); a warning is given when the record holds fewer than two repeats of the cycle. NULL uses tol instead. Default=NULL.
tol: Relative half-width of the period range (numeric, between 0 and 1; 0.05 means +/-5%), used only when record_length is NULL; NULL then uses 0.05. Default=NULL.
mult: Number of Rayleigh bandwidths used as half-width when record_length is given (numeric, > 0; 1 means +/-1 bandwidth). Default=1.
