asgardpy.gammapy.read_models module

Functions for reading different Models type objects with Gammapy objects.

asgardpy.gammapy.read_models.create_gal_diffuse_skymodel(diff_gal_file)[source]

Create SkyModel of the Diffuse Galactic sources either by reading a file or by using a provided Map object.

Parameters:

diff_gal_file (Path, gammapy.maps.Map) – Path to the isotropic diffuse model file, or a Map object already read from a file.

Returns:

  • model (gammapy.modeling.SkyModel) – SkyModel object read from a given galactic diffuse model file.

  • diff_gal (gammapy.maps.Map) – Map object of the galactic diffuse model

asgardpy.gammapy.read_models.create_iso_diffuse_skymodel(iso_file, key_name)[source]

Create a SkyModel of the Fermi Isotropic Diffuse Model and assigning name as per the observation key. If there are no distinct key types of files, the value is None.

Parameters:

  • iso_file (str) – Path to the isotropic diffuse model file

  • key (str) – Instrument key-name, if exists

Returns:

diff_iso – SkyModel object of the isotropic diffuse model.

Return type:

gammapy.modeling.SkyModel

asgardpy.gammapy.read_models.create_source_skymodel(source_info, dl3_aux_path, base_model_type='Fermi-XML', asgardpy_target_config=None)[source]

Build SkyModels from given base model information.

If AsgardpyConfig section of the target is provided for the target source information, it will be used to check if the target source_name is provided in the base_model file. If it exists, then check if the model information is to be read from AsgardpyConfig using from_3d boolean value. Also, if EBL model information is provided in the AsgardpyConfig, it will be added to the SkyModel object.

Parameters:

  • source_info (dict) – Dictionary containing the source models information from XML file.

  • dl3_aux_path (str) – Path location of the DL3 auxiliary files for reading Spatial Models from separate files.

  • base_model_type (str) – Name indicating the model format used to read the skymodels from.

  • asgardpy_target_config (AsgardpyConfig) – Config section containing the Target source information.

Returns:

  • source_sky_model (gammapy.modeling.SkyModel) – SkyModels object for the given source information.

  • is_source_target (bool) – Boolean to check if the Models belong to the target source.

asgardpy.gammapy.read_models.read_fermi_xml_models_list(list_source_models, dl3_aux_path, xml_file, diffuse_models, asgardpy_target_config=None)[source]

Read from the Fermi-XML file to enlist the various objects and get their SkyModels.

Parameters:

  • list_source_models (list) – List of source models to be filled.

  • dl3_aux_path (str) – Path location of the DL3 auxiliary files for reading Spatial Models from separate files.

  • xml_file (str) – Path of the Fermi-XML file to be read.

  • diffuse_models (dict) – Dict containing diffuse models’ filenames and instrument key.

  • asgardpy_target_config (AsgardpyConfig) – Config section containing the Target source information.

Returns:

  • list_source_models (list) – List of filled source models.

  • diffuse_models (dict) – Dict containing diffuse models objects replacing the filenames.

asgardpy.gammapy.read_models.update_aux_info_from_fermi_xml(diffuse_models_file_names_dict, xml_file, fetch_iso_diff=False, fetch_gal_diff=False)[source]

When no glob_search patterns on axuillary files are provided, fetch them from the XML file and update the dict containing diffuse models’ file names.

Parameters:

  • diffuse_models_file_names_dict (dict) – Dict containing the information on the DL3 files input.

  • xml_file (str) – Path of the Fermi-XML file to be read.

  • fetch_iso_diff (bool) – Boolean to get the information of the Isotropic diffuse model from the Fermi-XML file

  • fetch_gal_diff (bool) – Boolean to get the information of the Galactic diffuse model from the Fermi-XML file

Returns:

diffuse_models_file_names_dict – Dict containing the updated information on the DL3 files input.

Return type:

dict
