Dear all,

emission lines, one need to correct
stellar absorption for observed spectra,

I have a question about the 'output'

about the flux calibration of a spectrumStarted by:haha, 09/04/2014 03:49AM

Automatically there is a size for an

something of the aperture? Or we can
choose the size of the aperture by
ourself?

If we choose by hand, the flux may
