PHASEBIN

Name

phasebin

Purpose (one Line)

Compute a phase binned average lightcurve

Description

This routine bins lightcurve data as a function of time into a
binned composite lightcurve. Bins with no data are not returned.

Calling Sequence

phasebin,t,x0,sigx0,t0,period,nbins,rotphase,x,sig

Inputs

t - independent variable (usually time)
x0 - dependent variable (usually magnitude or intensity)
sigx0 - Uncertainty on x.
t0 - Reference time for 0 phase.
period- Rotational period to use when binning (same units as t).
nbins - Number of bins to break rotation into.

Optional Input Parameters

Keyword Parameters

Outputs

rotphase - Rotational phase for composite lightcurve.
x - composite lightcurve.
sig - Standard deviation of the mean in each bin.
chi2 - Goodness of fit to data within bin.
pop - Number of points in each bin.
