PROCEDURE: iug_load_gmag_stel_fluxgate To load the STEL fluxgate geomagnetic data from the STEL ERG-SC site NOTE: This procedure is a simple alias to "erg_load_gmag_stel_fluxgate" 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/magne/ and http://www1.osakac.ac.jp/crux/ (for mdm and tew). KEYWORDS: site = Observatory name, example, iug_load_gmag_stel_fluxgate, site='msr', the default is 'all', i.e., load all available stations. This can be an array of strings, e.g., ['msr', 'kag'] or a single string delimited by spaces, e.g., 'msr kag'. Sites for 1 sec data: msr rik kag ktb Sites for 1 min/h data: msr rik kag ktb mdm tew 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). /timeclip, if set, then data are clipped to the time range set by timespan EXAMPLE: iug_load_gmag_stel_fluxgate, site='msr kag', datatype='1min', $ 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)
