Detailed Description

Parse a jointcal logfile to extract chi2 values and plot them.

Call the instance with the path to a file to check it for anamolous chi2
and output plots to your current directory.

Parameters
----------
plot : `bool`
    Make plots for each file (saved to the current working directory)?
verbose : `bool`
    Print extra updates during processing?

Constructor & Destructor Documentation

__init__()

lsst.jointcal.check_logged_chi2.LogParser.__init__	(		self,
			plot = True,
			verbose = True )

Definition at line 89 of file check_logged_chi2.py.

Member Function Documentation

__call__()

lsst.jointcal.check_logged_chi2.LogParser.__call__	(		self,
			logfile )

Parse logfile to extract chi2 values and generate and save plots.

The plot output is written to the current directory, with the name
derived from the basename of ``logfile``.

Parameters
----------
logfile : `str`
    The filename of the jointcal log to process.

Definition at line 109 of file check_logged_chi2.py.

_extract_chi2()

lsst.jointcal.check_logged_chi2.LogParser._extract_chi2 ( self, opened_log, section )

protected

Return the values extracted from the chi2 statements in the logfile.

Definition at line 158 of file check_logged_chi2.py.

_find_chi2_increase()

lsst.jointcal.check_logged_chi2.LogParser._find_chi2_increase ( self, chi2Data, title, label, threshold = 1 )

protected

Return True and print a message if the raw chi2 increases
markedly.

Definition at line 141 of file check_logged_chi2.py.

_plot()

lsst.jointcal.check_logged_chi2.LogParser._plot ( self, astrometry, photometry, title )

protected

Generate plots of chi2 values.

Parameters
----------
astrometry : `Chi2Data` or None
    The as-read astrometry data, or None if there is none to plot.
photometry : `Chi2Data` or None
    The as-read photometry data, or None if there is none to plot.
title : `str`
    Title for the whole plot.

Definition at line 191 of file check_logged_chi2.py.

_plot_axes()

lsst.jointcal.check_logged_chi2.LogParser._plot_axes ( self, ax0, ax1, chi2Data, palette, label = "" )

protected

Make the chi2 and degrees of freedom subplots.
