Method Detail

getKeplPower

public static double[] getKeplPower(Kernel k1,
                                    double period,
                                    double M,
                                    boolean eccentric,
                                    int[] trials,
                                    double[] eccrange)

Calculates the power at a particular period according to the procedure by Cumming 2004. All the system information (star mass, RVs/residuals, etc.) are encoded in the kernel object k1 (a copy is made, so the state of k1 will not change).

Parameters:

k1 - The kernel object carrying the information about the system.

period - Period at which to search.

M - # of effective frequencies, to calculate FAP.

eccentric - whether to compute circular or eccentric periodogram

trials - array of {ecctrials, loptrials} (the size of the grid for the starting point eccs & lops)

eccrange - range of eccentricity

Returns:

an array containing {period, power, FAP}

fitAtPeriod

public static double[][] fitAtPeriod(Kernel k,
                                     double period,
                                     boolean eccentric,
                                     int[] trials,
                                     double[] eccrange)
