imgdisplay and dsplot support the definition of one or multiple regions
on displayed images (please consult the respective documentation if you are
not familiar with this feature). Region specifications can be propagated to
xmmselect by pushing a
button
in the main window. xmmselect shall read the regions from
imgdisplay/dsplot and
translate this into a corresponding selection expression which
will be appended to the current expression visible in the
entry field
at the top of the main window. The selection stage of a subsequent product
extraction will then merely consider events which lie inside/outside
any of the specified ``include''/``exclude'' regions.
Please note: Region markers with the color red will be ignored in this
process. This is useful in cases where one merely wants to import
a selected subset of all defined region markers. Please consult the
Ds9 documentation about how modify the properties of region markers.
