PROCEDURE: iug_load_gmag_mm210 to load the 210 MM geomagnetic data from the STEL ERG-SC site NOTE: This procedure is a simple alias to "erg_load_gmag_mm210" and calls the original one by just providing the same arguments/keywords given. Some load procedures for the ground-based observational data in the ERG mission, named "erg_load_???", can be also called by "iug_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/ See the rules of the road. For more information, see http://stdb2.stelab.nagoya-u.ac.jp/mm210/ KEYWORDS: site = Observatory name, example, iug_load_gmag_mm210, site='rik', the default is 'all', i.e., load all available stations. This can be an array of strings, e.g., ['rik', 'onw'] or a single string delimited by spaces, e.g., 'rik onw'.

'1min' for 1 min, and '1h' for 1 h. The default is '1min'. /downloadonly, if set, then only download the data, do not load it into variables. trange = (Optional) Time range of interest (2 element array). EXAMPLE: iug_load_gmag_mm210, site='rik onw', datatype='1min', $ trange=['2003-11-20/00:00:00','2003-11-21/00:00:00'] Written by: Y.-M Tanaka, Apr 22, 2010 (ytanaka at nipr.ac.jp) $LastChangedBy: jwl $ $LastChangedDate: 2014-01-22 15:54:40 -0800 (Wed, 22 Jan 2014) $ $LastChangedRevision: 13976 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/iugonet/load/iug_load_gmag_mm210.pro $
