RFS: fityk - general-purpose nonlinear curve fitting and data analysis

Hello All:

I am looking for a sponsor for the following package:

Package:        fityk
Author:         Marcin Wojdyr <wojdyr@if.pw.edu.pl>
URL:            http://www.unipress.waw.pl/soft/crystallography/fityk/
License:        GPL
Debian Packages:  deb-src http://fermi.phys.iit.edu/debian/sid source/
                  deb http://fermi.phys.iit.edu/debian/sid binary/


Fityk is a flexible and portable program for nonlinear fitting of analytical functions (especially peak-shaped) to data (usually experimental data). In other words, for nonlinear peak separation and analysis.

It was developed for analyzing diffraction patterns, but can be also used in other fields, since concepts and operations specific for crystallography are separated from the rest of the program.

Fityk offers various nonlinear fitting methods, subtracting background, calibrating data, easy placement of peaks and changing peak parameters, automation of common tasks with scripts, and much more. The main advantage of the program is a flexibility - parameters of peaks can be arbitrarily binded with each other, eg. width of peak can be an independent variable, can be the same as width of other peak or can be given by complicated - common for all peaks - formula.

The package is lintian clean and can be built on i386 with pbuilder.
