AHELP for Sherpa 4.0 Beta ignore2d_id Context: sl.sherpa

Synopsis

Ignore 2D data with a region filter by data set ID(s).

Syntax

ignore2d_id( ids; [val] );

Description

Exclusive ignore on 2D data using a region filter for the supplied data set ID(s)

Example

sherpa> ignore2d_id(1);
sherpa> ignore2d_id(1, "circle(25,25,5)");
sherpa> ignore2d_id([2,4], "circle(4300,3710,15)");
sherpa> ignore2d_id(1, "circle(259.18823,67.14189,0.01)");
sherpa> ignore2d_id("psf", filter.reg);

The function ignore2d_id can be called with only one argument, in which the filter will ignore all data points on the grid for all the supplied 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 the list of supplied data set ID(s).
