I have quasar spectrum which includes emission and absorption lines. I need to find absorption lines in between 2 wavelength. How can I do it with coding?

    $\begingroup$ Is the spectrum in a data file or is it just an image? $\endgroup$ – Natsfan Feb 12 '20 at 17:14
  • $\begingroup$ That is a data file. $\endgroup$ – Sara Feb 13 '20 at 5:46
  • $\begingroup$ In which energy range is your spectrum? Which environment / language are you using for the analysis? Do you already know the number, energies or widths of the absorption lines? $\endgroup$ – SpaceCore Feb 13 '20 at 11:33
  • $\begingroup$ Is the x-axis energy ( wavelength, frequency) and y-axis intensity. $\endgroup$ – Natsfan Feb 13 '20 at 16:02
