3.15 The generate spectra from interpolated lines window
This window is for generating a spectrum that is equivalent to an interpolated line that you have
drawn (or are about to draw) on the plot. Such lines can then be subtracted to or from, or divided into
the current spectrum, thus providing a way to background correct a spectrum using a hand-drawn
- Draw Curve Start an interaction in the plot window for drawing a curve. This is
equivalent to selecting the Drawing mode-> option in the Graphics menu. Different
types of interpolated lines can be selected first in the Curve type menu. The default is
hermite a type of spline that attempts to connect points in a similar way to a hand-drawn
- Generate Generates an actual spectrum from your interpolated curve and then displays
it, along with any subtracted or divided spectra, in the plot.
- Generate (Replace) Same as Generate, except that if you’ve opted to subtract or divide
the curve into the displayed spectrum, then that spectrum will be removed and you’ll
only see the subtracted and/or divided result. If you haven’t opted to subtract or divide
then the results are exactly the same as for Generate.
- Reset Removes any spectra that you’ve generated from the plot and global list.
- Reset (Replace) Same as Reset, but it also restores the spectrum removed in by the first
Generate (Replace). Effectively undoes a Generate (Replace).
- Control-d Start interaction to draw a curve.
- Control-g Generate a spectrum from the drawn curve.
- Control-p Reset interface undoing a Generate (Replace).
- Control-r Reset interface clearing all new spectra.
- Control-i Delete any new spectra.
- Control-w Close the window.
- F1 Display help on SPLAT-VO.
- Shift-F1 Display help on window.
