Populations is an easy to use computer program for plotting several 1D curves or mathematical expressions of those curves modified by parameters (scale and background factors, for example).

The values of the parameters can then be fitted to another curve or to an expression. The parametere values can be limited by constraints. The results can be exported as text files.  

The program was developed and tested by Avi Ginsburg and Uri Raviv from the Institute of Chemistry at the Hebrew University of Jerusalem.
