PROCEDURE: ERG_LOAD_GMAG_NIPR erg_load_gmag_nipr, site = site, $ datatype=datatype, $ trange=trange, $ verbose=verbose, $ downloadonly=downloadonly no_download=no_download PURPOSE: Loads the fluxgate magnetometer data obtained by NIPR. NOTE: This procedure is a simple alias to "iug_load_gmag_nipr" and calls the original one by just providing the same arguments/keywords given. Some load procedures for the ground-based observational data in the IUGONET projetct, named "iug_load_???", can be also called by "erg_load_???", because these data are related to the both ERG and IUGONET projects. For more information, see http://www.iugonet.org/en/ and http://gemsissc.stelab.nagoya-u.ac.jp/erg/ KEYWORDS: site = Observatory name, example, erg_load_gmag_nipr, site='syo', the default is 'all', i.e., load all available stations. This can be an array of strings, e.g., ['syo', 'hus'] or a single string delimited by spaces, e.g., 'syo hus'. Available sites: syo hus tjo aed isa datatype = Time resolution. Please notice that '1sec' means nearly 1-sec time resolution. Even if datatype was set to '1sec', the time resolution corresponds to 2sec : syo(1981-1997), hus & tjo(1984-2001/08), isa(1984-1989), aed(1989-1999/10) 1sec : syo(1997-present) 0.5sec : hus & tjo(2001/09-present), aed(2001/09-2008/08) Available datatype: 1sec(default) or 20hz trange = (Optional) Time range of interest (2 element array). /verbose : set to output some useful info /downloadonly: if set, then only download the data, do not load it into variables. /no_download: use only files which are online locally. EXAMPLE: erg_load_gmag_nipr, site='syo', $ trange=['2003-11-20/00:00:00','2003-11-21/00:00:00'] Written by Y.-M.
