get_station

Initialize the stations detector properties. By default, a new detector instance is only created of none exists yet, otherwise the existing instance is returned. To force the creation of a new detector instance, pass the additional keyword parameter create_new=True to this function. For more details, check the documentation for the Singleton metaclass.

Parameters:

sourcestr: ‘json’, ‘dictionary’ or ‘sql’ default value is ‘json’ if dictionary is specified, the dictionary passed to __init__ is used if ‘sql’ is specified, the file ‘detector_sql_auth.json’ file needs to be present in this folder that specifies the sql server credentials (see ‘detector_sql_auth.json.sample’ for an example of the syntax)
json_filenamestr: the path to the json detector description file (if first checks a path relative to this directory, then a path relative to the current working directory of the user) default value is ‘ARIANNA/arianna_detector_db.json’
assume_infBool: Default to True, if true forces antenna models to have infinite boundary conditions, otherwise the antenna madel will be determined by the station geometry.
antenna_by_depth: bool (default True): if True the antenna model is determined automatically depending on the depth of the antenna. This is done by appending e.g. ‘_InfFirn’ to the antenna model name. if False, the antenna model as specified in the database is used.
create_new: bool (default:False): Can be used to force the creation of a new detector object. By default, the __init__ will only create a new object if none already exists.
