Request for example on reading the fluxes file

[jon-proximafusion]

Hi there

Just taking a look at this package after a long time and I am trying to read in a fluxes file like this one

https://www-nds.iaea.org/conderc/fusion/element/Cr/files/2000exp_5min_fluxes

By any chance pypact has a nice convenient way of reading it in?

Hi there

i think it may be possible with the pypact.FluxesFile() and pypact.from_file. There is also a ArbFluxesFile() for another type of historical (?) flux file structure (see examples/groupconvert).

After reading the file in one can access energy boundaries, midpoint energies, values, the name and norm. Then one could convert it in another group structure from the pre-defined ones. There is also a spectrum_lib.json where the spectrum could probably be saved (havent tried it).

Cheers

Here is a simple example for fluxes files that are in one of the FISPACT predefined groups.

import pypact as pp

ff = pp.FluxesFile()
pp.from_file(ff, 'Cr_2000exp_5min_fluxes')
energy_bound_ascending, bin_values = ff.boundaries, ff.values

For custom energy structures you will need the ArbFluxesFile. But the file you point out is in 709 group it works fine as above.

As @PeBoch points out there are some examples on this, but they're not well documented. I'll see if I can make this clearer in the docs and examples.

Many thanks both. This works well for me. Now plotting those fluxes files is super easy.
