gstlal_psd_polyfit
==================

A program to fit a PSD to a polynomial


Usage cases
-----------

1. Fit a PSD to a polynomial with default settings (consider using gstlal_plot_psd to compare the results)::

	$ gstlal_psd_polyfit --output smooth.xml.gz H1refpsd.xml.gz


2. Please add more


Command line options

   Options:
     -h, --help            show this help message and exit
     --median-window=MEDIAN_WINDOW
                           Median window in sample points to apply running median
                           for removing sharp features. Default 8.  Setting it to
                           1 effectively disables this filter.
     --output=filename     Set the name of the LIGO light-weight XML file to
                           output
     --poly-order=POLY_ORDER
                           Set the order of the fitting polynomial. default 10
     --low-fit-freq=LOW_FIT_FREQ
                           Set the low frequency at which to begin fitting in Hz.
                           default 30
     --high-fit-freq=HIGH_FIT_FREQ
                           Set the high frequency at which to stop fitting in Hz.
