SynopsisNotice 2D data with a region filter. Syntaxnotice2d( [val] ) DescriptionExclusive notice on 2D data using a region filter for all available data set ID(s). Example
sherpa> notice2d()
sherpa> notice2d("circle(25,25,5)")
sherpa> notice2d("circle(4300,3710,15)")
sherpa> notice2d("circle(259.18823,67.14189,0.01)")
sherpa> notice2d(filter.reg)The function notice2d can be called with no arguments, in which case the filter will notice 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).
