PROCEDURE: IUG_LOAD_EISCAT_VIEF iug_load_eiscat_vief, site=site, $ get_support_data=get_support_data, $ trange=trange, $ verbose=verbose, $ downloadonly=downloadonly, $ no_download=no_download PURPOSE: loads the EISCAT vector Vi and E field data. KEYWORDS: site = site code, example, iug_load_eiscat_vief, site='kst', the default is 'all', i.e., load all available sites. Available sites: 'kst' (kst means Kiruna, Sodankyla, Tromso.) trange = (Optional) Time range of interest (2 element array). /get_support_data : turn this on to load the supporting data. /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. OUTPUT Vi and E vectors have 3 components, i.e., Vi = [Ve, Vn, Vu] and E = [Ee, En, Eu], where [e, n, u] corresponds to [eastward, n:northward, u:upward]. EXAMPLE: iug_load_eiscat_vief, site='kst', $ trange=['2011-2-1/00:00:00','2011-2-3/00:00:00'] For more information, see http://www.iugonet.org/en/ and http://polaris.nipr.ac.jp/~eiscat/eiscatdata/ Written by: Y.-M.
