  • suffix (str, optional) – The tplot variable names will be given this suffix. Default is no suffix is added.

  • get_support_data (bool, optional) – Data with an attribute “VAR_TYPE” with a value of “support_data” will be loaded into tplot. Default is only loads in data with a “VAR_TYPE” attribute of “data”.

  • varformat (str, optional) – The file variable formats to load into tplot. Wildcard character “*” is accepted. Default is all variables are loaded in.

  • varnames (list of str, optional) – List of variable names to load. Default is all data variables are loaded.

  • downloadonly (bool, optional) – Set this flag to download the CDF files, but not load them into tplot variables. Default is False.

  • notplot (bool, optional) – Return the data in hash tables instead of creating tplot variables. Default is False.

  • no_update (bool, optional) – If set, only load data from your local cache. Default is False.

  • time_clip (bool, optional) – Time clip the variables to exactly the range specified in the trange keyword. Default is False.

  • force_download (bool, optional) – Download file even if local version is more recent than server version. Default is False.

Returns:

List of tplot variables created. If notplot is set to True, returns a list of dictionaries containing the data. If downloadonly is set to True, returns a list of the downloaded files.

Return type:

Parameters:

  • trange (list of str, optional) – Time range of interest [starttime, endtime] with the format [‘YYYY-MM-DD’,’YYYY-MM-DD’] or to specify more or less than a day [‘YYYY-MM-DD/hh:mm:ss’,’YYYY-MM-DD/hh:mm:ss’]. Default is [“1982-12-06”, “1982-12-07”]. Data is available only for years 1981, 1982, 1983.

  • instrument (str, optional) – Valid options are: ‘mag’, ‘nacs’, ‘rpa’, ‘idm’, ‘wats’, ‘vefi’, ‘lang’. Default is ‘mag’. Each instrument has only one datatype available, so the datatype is not a keyword option.

  • prefix (str, optional) – The tplot variable names will be given this prefix. Default is no prefix is added.

  • suffix (str, optional) – The tplot variable names will be given this suffix. Default is no suffix is added.

  • get_support_data (bool, optional) – Data with an attribute “VAR_TYPE” with a value of “support_data” will be loaded into tplot. Default is only loads in data with a “VAR_TYPE” attribute of “data”.

  • varformat (str, optional) – The file variable formats to load into tplot. Wildcard character “*” is accepted. Default is all variables are loaded in.

  • varnames (list of str, optional) – List of variable names to load. Default is all data variables are loaded.

  • downloadonly (bool, optional) – Set this flag to download the CDF files, but not load them into tplot variables. Default is False.

  • notplot (bool, optional) – Return the data in hash tables instead of creating tplot variables. Default is False.

  • no_update (bool, optional) – If set, only load data from your local cache. Default is False.

  • time_clip (bool, optional) – Time clip the variables to exactly the range specified in the trange keyword. Default is False.

  • force_download (bool, optional) – Download file even if local version is more recent than server version. Default is False.

Returns:

List of tplot variables created. If notplot is set to True, returns a list of dictionaries containing the data. If downloadonly is set to True, returns a list of the downloaded files.

Return type:

list
