----
The code is written in Python, tested to be working under Linux and Windows with Python 2.7/3.5. There is no required NumPy dependency, but it still can be used for operations with matrices, etc. (see the `Usage` section below).
Determine Delta/Attenuation length:
-
To create a `.dat` file with the refractive index decrement or the attenuation length, use the following commands respectively:
```bash
bnlcrl simulate find-delta --characteristic delta -f Al -o Al_delta.dat 30
```
```bash
bnlcrl simulate find-delta --characteristic atten -f Al -o Al_atten.dat 30
```
Usage:
-
```
$ bnlcrl simulate find-delta -h
usage: bnlcrl simulate find-delta [-h] [--calc-delta]
[--characteristic {atten,delta}]
[-d DATA_FILE] [--e-max E_MAX]
[--e-min E_MIN] [--e-step E_STEP]
[-f FORMULA] [-n N_POINTS] [-o OUTFILE] [-p]

energy
Determine the Index of Refraction (delta).
The index of refraction can be defined by three different methods/approaches:
1) Get delta for the closest energy from the saved *.dat files (see ``bnlcrl/package_data/dat/``).
2) Get delta from http://henke.lbl.gov/optical_constants/getdb2.html.
3) Calculate delta analytically (requires ``periodictable`` package installed).
Args:
calc_delta (bool): a flag to calculate delta analytically.
characteristic (str): characteristic to be extracted (``atten`` - attenuation length, ``delta`` - index of refraction).
data_file (str): a *.dat data file in ``bnlcrl/package_data/dat/`` directory with delta values for the material of the CRL (e.g., Be).
e_max (float): the highest available energy [eV].
e_min (float): the lowest available energy [eV].
e_step (float): energy step size used for saving data to a file [eV].
energy (float): photon energy [eV].
formula (str): material's formula of the interest.
n_points (int): number of points to get from the server.
outfile (str): optional output file.
precise (bool): a flag to find delta within the energy interval +/- 1 eV from the specified energy.
use_numpy (bool): a flag to use NumPy.
verbose (bool): a flag to print output to console.
Returns:
dict: dictionary with the result.
