contour_resid

Synopsis

Open a contour plot of data-minus-model residuals in ChIPS

contour_resid( [ id, [replot=False,overcontour=False]] )

Description

The contour_resid function opens in ChIPS a contour plot of fit residuals (dataset minus dataset model) by data set ID. If no data set ID is specified, the residuals corresponding to the default data set will be used. To plot contours of a data set, model, fit, data-to-model ratio, or psf, use the contour function.

Arguments:

• id - Sherpa data set ID; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
• replot - Send cached data arrays to ChIPS; default=False
• overcontour - Contour data without clearing previous plot; default=False

Example 1

sherpa> contour_resid()

The contour_resid function can be called with no arguments, in which case a contour plot of the data-minus-model fit residuals is made for the default data set loaded in the Sherpa session, with the default settings.

Example 2

sherpa> contour_resid(3, overcontour=False)

Here, the contour_resid function clears the previous plot and sends to ChIPS a contour plot of the fit residuals associated with data set 3.

Example 3

sherpa> contour_resid(replot=True, overcontour=True)

This command sends to ChIPS a cached contour plot of the fit residuals of the default dataset, without clearing the previous plot.
