AmiLgModel

class jwst.datamodels.AmiLgModel(init=None, schema=None, memmap=False, pass_invalid_values=None, strict_validation=None, ignore_missing_extensions=True, **kwargs)[source]

Bases: jwst.datamodels.DataModel

A data model for AMI LG analysis results.

Parameters
  • fit_image (numpy float32 array) – Fitted image

  • resid_image (numpy float32 array) – Residual image

  • closure_amp_table (numpy table) – Closure amplitudes table

  • closure_phase_table (numpy table) – Closure phases table

  • fringe_amp_table (numpy table) – Fringe amplitudes table

  • fringe_phase_table (numpy table) – Fringe phases table

  • pupil_phase_table (numpy table) – Pupil phases table

  • solns_table (numpy table) – Solutions table

  • init (str, tuple, HDUList, ndarray, dict, None) –

    • None : Create a default data model with no shape.

    • tuple : Shape of the data array. Initialize with empty data array with shape specified by the.

    • file path: Initialize from the given file (FITS or ASDF)

    • readable file object: Initialize from the given file object

    • HDUList : Initialize from the given HDUList.

    • A numpy array: Used to initialize the data array

    • dict: The object model tree for the data model

  • schema (dict, str (optional)) – Tree of objects representing a JSON schema, or string naming a schema. The schema to use to understand the elements on the model. If not provided, the schema associated with this class will be used.

  • memmap (bool) – Turn memmap of FITS file on or off. (default: False). Ignored for ASDF files.

  • pass_invalid_values (bool or None) – If True, values that do not validate the schema will be added to the metadata. If False, they will be set to None. If None, value will be taken from the environmental PASS_INVALID_VALUES. Otherwise the default value is False.

  • strict_validation (bool or None) – If True, schema validation errors will generate an exception. If False, they will generate a warning. If None, value will be taken from the environmental STRICT_VALIDATION. Otherwise, the default value is False.

  • ignore_missing_extensions (bool) – When False, raise warnings when a file is read that contains metadata about extensions that are not available. Defaults to True.

  • kwargs (dict) –

    Additional keyword arguments passed to lower level functions. These arguments are generally file format-specific. Arguments of note are:

    • FITS

      skip_fits_update - bool or None

      True to skip updating the ASDF tree from the FITS headers, if possible. If None, value will be taken from the environmental SKIP_FITS_UPDATE. Otherwise, the default value is True.

Methods Summary

get_primary_array_name()

Returns the name “primary” array for this model, which controls the size of other arrays that are implicitly created.

Methods Documentation

get_primary_array_name()[source]

Returns the name “primary” array for this model, which controls the size of other arrays that are implicitly created. This is intended to be overridden in the subclasses if the primary array’s name is not “data”.
