PROCEDURE: iug_load_gmag_magdas_1sec PURPOSE: To load the MAGDAS geomagnetic data from the STEL ERG-SC site NOTE: This procedure is a simple alias to "erg_load_gmag_magdas_1sec" 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://magdas.serc.kyushu-u.ac.jp/ KEYWORDS: site = Observatory name, example, iug_load_magdas_1sec, site='asb', the default is 'all', i.e., load all available stations. This can be an array of strings, e.g., ['asb', 'onw'] or a single string delimited by spaces, e.g., 'asb onw'. Sites for 1 sec data: asb ... Sites for 1 min/h data: ... datatype = Time resolution. '1sec' for 1 sec', '1min' for 1 min, and '1h' for 1 h. The default is 'all'. If you need two of them, set to 'all'. /downloadonly, if set, then only download the data, do not load it into variables. /no_server, use only files which are online locally. /no_download, use only files which are online locally. (Identical to no_server keyword.) trange = (Optional) Time range of interest (2 element array). EXAMPLE: iug_load_gmag_magdas_1sec, site='asb onw', datatype='1sec', $ trange=['2003-11-20/00:00:00','2003-11-21/00:00:00'] Written by: Y.-M Tanaka, Feb. 5, 2014 (ytanaka at nipr.ac.jp)
