Algorithm

Create a source spectrum 
     
   expression = <srcexp> + PATTERN + FLAG selections
   evselect table=<table> expression=<expression> 
            withspectrumset=yes spectrumset=<filestem>+"_src.ds"

Create a background spectrum

   expression = <backexp> + PATTERN + FLAG selections
   evselect table=<table> expression=<expression>......
            withspectrumset=yes spectrumset=<filestem>+"_bgd.ds"

Create an ARF for the source spectrum and calculate the source box area

   arfgen spectrumset=<srcspec> arfset=<arfset> withrmfset=<withrmfset>
          rmfset=<rmfset> extendedsource=<extendedsource> 
          withbadpixcorr=<withbadpixcorr> badpixlocation=<table> 
          setbackscale=yes keeparfset=yes useodfatt=<useodfatt>

Use arfgen to calculate the background box area

   arfgen spectrumset=<backspec> arfset=temparf.arf setbackscale=yes 
          keeparfset=no withbadpixcorr=<withbadpixcorr> 
          badpixlocation=<table> useodfatt=<useodfatt>

Create an RMF if not supplied
   if (! <withrmfset>) {
      rmfgen spectrumset=<srcspec> rmfset=<rmfset>
   }
