SSIM

The flux from a spectral model is calculated, folded through an instrument response and a background spectrum and Poisson noise are optionally added, to give a simulated spectral observation. Since results are given in count/sec the observation time need only be specified where Poisson errors are to be included.

The input file can be any object which contains an instrument response (it need not be a SPECTRUM). Channel values for the simulated spectrum are taken from the response structure itself. If a redshift is currently set then it will be applied to the model (you will be informed if a non-zero redshift is in force). A new redshift can be specified on the command line.

The output file becomes the current binned dataset and so can be displayed by typing GDRAW.
