Download, Requirements and Installation (Perl Version)
The last stable Perl version of FIT3D can be download here.

FIT3D Perl version requires the following perl modules to be installed in your computer:

Statistics::OLS
Math::FFT
Math::Stat
Math::Spline qw(spline linsearch binsearch)
Math::Derivative qw(Derivative2)
Math::Approx
Astro::FITS::CFITSIO qw( :longnames :constants )
PGPLOT
PDL

All this modules can be found at CPAN. It is recomended the lastest possible version of PDL.

You need to define an environmental variable, FIT3D_PATH with the directory of your installation. E.g.,
setenv FIT3D_PATH "/home/sanchez/sda2/code/FIT3D" for tcshell
export FIT3D_PATH="/home/sanchez/sda2/code/FIT3D"; for Bash shell

If you do not get any error or warning message you have suscessfully installed FIT3D. Then, add the directory DIR to your PATH. If you find any problem, please send an email to S.F.Sanchez
