4.12.2.2 Inspection of spectra or timeseries using the command line

Although xmmselect interacts in a convenient way with the external plotting program grace, the user might want to plot, inspect or export spectra and timeseries which have been created in an already closed xmmselect session or via evselect from the command line. As the produced output files are FITS files, the FTOOLS task fv and fplot offer many possibilities here, but also the SAS task dsplot can be used:

• The spectra or timeseries table can be plotted with the grace package using the dsplot command. We assume that the spectrum or timeseries are named product.fits:

   
  dsplot table=product.fits
  

• Postscript files can be created.

  dsplot table=product.fits plotter='gracebat -printfile product.ps'
  

• Spectrum and timeseries files can also be generated in ASCII format using the command dstoplot.

  dstoplot table=product.fits > product.asc
