deesse_loader module

Define a loader adapted to DEESSE (ONERA, Toulouse) file format.

class DeesseLoader

Bases: Loader

Define the loader.

__init__() → None

Raise an error for now.

Ideally, this loader should detect correct input and columns. But it is not for now.

load_emission_yield(*filepath: str | Path) → DataFrame

Load and format the given emission yield files.

Parameters:: filepath – Path(s) to file holding data under study.
Returns:: Structure holding the data. Has a Energy [eV] column holding PEs energy. And one or several columns theta [deg], where theta is the value of the incidence angle and content is corresponding emission yield.
Return type:: pandas.DataFrame

_extract_incidence_angle(full_data: DataFrame) → float: Try to get the incidence angle in the file.

load_emission_angle_distribution(*args) → Any: Load the given electron emission angle distribution file.

load_emission_energy_distribution(filepath: str | Path, e_pe: float | None = None) → tuple[DataFrame, float | None]

Load and format an emission energy file from DEESSE.

Parameters:

filepath – Path to file holding data under study.
e_pe – Energy of PEs in \(\mathrm{eV}\). Should be manually provided, as not present in DEESSE files.

Returns:

pandas.DataFrame – Structure holding the data. Has a Energy [eV] column holding emitted electrons energy. And one or several columns theta [deg], where theta is the value of the incidence angle and content is corresponding emission energy distribution.
float – Energy of Primary Electrons in \(\mathrm{eV}\). If not found in the file comments, it will be inferred from the position of the EBEs peak.
