Adding noise to Raw Spectrum
rohit wrote on Jul 23, 2008
Hi All,
We are trying to simulate observation when S/N is quite low something like 10. To do so, I was thinking of adding noise to the raw files we have obtained. These are echelle spectrum files. How do I add noise to these files such that after reduction, I get a noisy spectrum?
Thanks for your help

See if the MKNOISE task in the ARTDATA package will do what you need.
