To enhance or not?

[Gasman]

Hi guys

I often wonder how much, if any post processing to do to spectra. I find it a bit of a juggling act using some of the post processing packages out there- Am I bringing out faint detail that wouldn`t normally be seen or creating artifacts that shouldn`t really be there?

For instance this a raw spectrum I took some time ago of P Cyg uncalibrated just input as taken in fits and the same spectrum slightly enhanced in tiff format using a package called On1.

No smoothing was done but you can clearly see a difference in the unprocessed peaks and also some slight difference in detail of the profiles so care must be taken . I suppose it could be argued not to do any processing at all to the fits but I`d be interested in what you folks think.

cheers
