0vßß– Hierarchy Graph

Just a short update from me today, since my last blog i have found a suitable graph producing library for PHP (a web based programming language), and collated the data that needs to be plotted.

In the background of the plots I needed to plot the theoretical allowed values- this presented a challenge, as none of the academics in the department remebered how! However after a trawl through papers, and a week of fiddling and coding i was able to produce the graph below, in the correct form, and generating the curves on the fly, so eventually the user will be able to change the paramters at will!

0vßß – Week Three

And so another week begins (or, has already done so). After Sam and I submitted a design document last week (which basically detailed how we plan to set out the design of the program we are eventually to write) we started to look at implementation issues. There are several rather evil looking equations which we must implement in C++ (a computer programming language) in order to obtain the angular distributions and energies of the particles released from a double beta decay event.

Yesterday we obtained some existing code that does more or less the same thing, and stared at it in horror and disgust (Fortran; don’t touch it… ever!) Today will probably involve picking through it for the parts that implement those nasty equations! Fun!

To the work Cave!
