5. Windowed Multipole Library Format¶
/
- Attributes
filetype (char[]) – String indicating the type of file
version (int[2]) – Major and minor version of the data
/<nuclide name>/
- Datasets
- broaden_poly (int[])
If 1, Doppler broaden curve fit for window with corresponding index. If 0, do not.
- curvefit (double[][][])
Curve fit coefficients. Indexed by (window index, coefficient index, reaction type).
- data (complex[][])
Complex poles and residues. Each pole has a corresponding set of residues. For example, the \(i\)-th pole and corresponding residues are stored as
\[\text{data}[:,i] = [\text{pole},~\text{residue}_1,~\text{residue}_2, ~\ldots] \]The residues are in the order: scattering, absorption, fission. Complex numbers are stored by forming a type with “\(r\)” and “\(i\)” identifiers, similar to how h5py does it.
- E_max (double)
Highest energy the windowed multipole part of the library is valid for.
- E_min (double)
Lowest energy the windowed multipole part of the library is valid for.
- spacing (double)
- \[\frac{\sqrt{E_{max}} - \sqrt{E_{min}}}{n_w} \]
Where \(E_{max}\) is the maximum energy the windows go up to. \(E_{min}\) is the minimum energy, and \(n_w\) is the number of windows, given by
windows.
- sqrtAWR (double)
Square root of the atomic weight ratio.
- windows (int[][])
The poles to start from and end at for each window. windows[i, 0] and windows[i, 1] are, respectively, the indexes (1-based) of the first and last pole in window i.
