[GRASS-user] î.evapo.potrad negative ETpot values

Over the past few months I used i.evapo.potrad, in order to calculate 
ETpot. Now, this module yields erratic negative values. Is it possible 
for me as a ordinary user to extract the mathematics behind 
i.evapo.potrad somewhere so that I could calculate ETpot with a script, 
which I write by myself ?

thanks for help
