AHELP for Sherpa 4.0 Beta ignore2d Context: py.sherpa

Synopsis

Ignore 2D data with a region filter.

Syntax

ignore2d( [val] )

Description

Exclusive ignore on 2D data using a region filter for all available data set ID(s).

Example

sherpa> ignore2d()
sherpa> ignore2d("circle(25,25,5)")
sherpa> ignore2d("circle(4300,3710,15)")
sherpa> ignore2d("circle(259.18823,67.14189,0.01)")
sherpa> ignore2d(filter.reg)

The function ignore2d can be called with no arguments, in which case the filter will ignore all data points on the grid for all available data set ID(s). Supplying a region string or file containing a region string will apply a filter to the stack. It is important to note that coordinate system in the region string must match the coordinate system in the data set. The coordinate values in the region string will be applied using the grid(s) in all the available data set ID(s).

Bugs

See the bugs pages on the Sherpa Beta website for an up-to-date listing of known bugs.
