how to use phase_proc_lp to get a new kdp field

[johnnypeste]

Hi

I several scientific articles I saw that "phase_proc_lp" is present in py_art to get a potential improved kdp field

I saw examples using vulpiani, that works like this:

kdp_vulpiani = pyart.retrieve.kdp_vulpiani(radar, band='C', parallel=True)
radar.add_field('kdp_vulpiani', kdp_vulpiani[0])
radar.add_field('phidp_vulpiani', kdp_vulpiani[1])

but I cannot find an example how to use the well famed "phase_proc_lp"
