◆ compute_fwhmrange()

lsst.meas.extensions.psfex.psfex.compute_fwhmrange ( fwhm,
maxvar,
minin,
maxin,
plot = dict(fwhmHistogram=False) )
Compute the FWHM range associated to a series of FWHM measurements.
    AUTHOR  E. Bertin (IAP, Leiden observatory & ESO)
    VERSION 20/03/2008

Parameters
----------
fwhm: iterable of `float`
    Iterable of full width half-maxima.
maxvar: `float`
    Maximum allowed FWHM variation.
minin: `float`
    Minimum allowed FWHM.
maxin: `float`
    Maximum allowed FWHM.
plot: `dict`, optional
    Dict of plotting options.

Returns
-------
fmin: `float`
    FWHM mode.
minout: `float`
    Lower FWHM range.
maxout: `float`
    Upper FWHM range.
