What is this?

Put liquid nitrogen in a vacuum chamber. Turn on the pump. Enjoy. I wrote about 5 pages of theory, I might put them up later for reference :)

Compile

make

Clean

make clean

Run

Run Simulation

./liquid_n2_fitting

Run fit (interactive)

./liquid_n2_fitting fit

Alternative:

Use Codeblocks and open Project File

plot data with gnuplot

gnuplot gp_script.plt

The resulting filename will be "fit_plot.eps". Feel free to change the script to suit your needs ;-)
