ctools

Hi, I am Christian Diaz and I have a problem with the last update of CTools, this is: when I use the console to plot the spectrums by different simulations (with a different version of ctools), doesn’t work and show me this bug:
---------------
"(chirri) Christians-MacBook-Pro:Graphs chirri$ python show_spectrum.py SpecedispWoALPs1.fits

Traceback (most recent call last):

File "show_spectrum.py", line 296, in <module>

show_spectrum()

File "show_spectrum.py", line 284, in show_spectrum

plot_spectrum(args[0], plotfile)

File "show_spectrum.py", line 230, in plot_spectrum

spec = get_spectrum_file(filename)

File "show_spectrum.py", line 59, in get_spectrum_file

return get_spectrum_fits(fits)

File "show_spectrum.py", line 81, in get_spectrum_fits

c_energy = table['e_ref']

File "/Users/chirri/opt/anaconda3/envs/chirri/lib/python3.5/site-packages/gammalib/fits.py", line 2279, in getitem

return fits.GFitsTable__getitem__(self, *args)

RuntimeError: *** ERROR in GFitsTable::operator[](std::string&): Column “e_ref” not found in table”

I saw the file show_spectrum.py and I realized that is very different than the old version of the file show_spectrum.py, so you have some advice for that or some solution?

Best regards.
