-Dear Quanty developpers,I was inspired by the tutorial for the calculation of partial excitation at the L_{2,3}$ edge of NiO for writing a script for XAS at the M_{4,5}$ edge of cerium with configuration-interaction.+Dear Quanty developpers,I was inspired by the tutorial for the calculation of partial excitation at the $L_{2,3}$ edge of NiO for writing a script for XAS at the $M_{4,5}$ edge of cerium with configuration-interaction.
 I would like to look at excitations into the $f^0$, $f^1$ and $f^2$ configurations but there is some problems. I would like to look at excitations into the $f^0$, $f^1$ and $f^2$ configurations but there is some problems.

 +A note further important information to know is that the spectrum is calculated with restrictions set in the following way

 +NConfigurations = 3
 +CalculationRestrictions = {NF, NB, {'0000000000 00000000000000 11111111111111', 14 - (NConfigurations - 1), 14}}
