<div dir="ltr">hi,<br><br>Is there any handy module to detect emission lines in a spectrum like one we get from sdss?The spectra of sloan are fits files and the wavelength calibration has been done.Suppose the redshift is smaller than 300km/s<br>
<br>Case A:<br>We have a spectral line list.We just want to know whether there are some kinds of emission lines in the fits files.<br><br>Case B:<br>We do not have a line list.We just want to detect emission lines.<br><br>
Thank you.<br>hang<br></div>
