HOW TO ADD NEW TABLES: 1- Specification a) tables for atmospheric neutrinos: the tables which are read by the constructor (described in 1-a) consist of the parameters of a bidimensional fitting of the original tables of fluxes. The fitting is done using a 5-degree polynomial. For further specification about the fitting see http://www.icecube.wisc.edu/~tamburro/fitting.html or http://www.icecube.wisc.edu/~tmontaruli/fitting.html The tables are formatted as follows (OUTDATED - this format is good for prompt fluxes only) ------------------------------------------------------ |Parameters Error on the parameters (not used yet)| | par[0] pare[0] | | ........ ................ | | par[14] pare[14] | ------------------------------------------------------ b) tables of astrophysical neutrinos: for a complete explanation of how to format correctly this type of tables see http://www.icecube.wisc.edu/~tamburro/NeutrinoFlux.html or http://www.icecube.wisc.edu/~tmontaruli/NeutrinoFlux.html The user can add a diffuse flux model (file name "user_diffuse.dat") or a point-like flux model (file name "user_point.dat"). These fluxes are defined in a number of energy intervals (variable "piece_" read from files).

2- Insert the new table in the directory specified by FLUXTABLES
