PROCEDURE: IUG_LOAD_EISCAT iug_load_eiscat, site=site, $ ydatatype=ydatatype, $ get_support_data=get_support_data, $ trange=trange, $ verbose=verbose, $ downloadonly=downloadonly, $ no_download=no_download PURPOSE: loads the EISCAT radar data. KEYWORDS: site = Combination of observatory and antenna, example, iug_load_eiscat, site='esr_42m', the default is 'all', i.e., load all available sites. Available sites: 'tro_uhf', 'tro_vhf', 'esr_32m', 'esr_42m'. This can be an array of strings, e.g., ['esr_32m', 'esr_42m'] or a single string delimited by spaces, e.g., 'esr_32m esr_42m'. ydatatype = data type of y-axis. Default is 'alt', i.e., altitude. 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. EXAMPLE: iug_load_eiscat, site='esr_42m', $ 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.

Tanaka, December 1, 2011 to load data with various int_times separately to different tplot vars. Modified by: Y.-M. Tanaka, June 6, 2012 Integragted all pulse_code and integration_time data for one day into a CDF file Modified by: Y.-M. Tanaka, August 16, 2013 Added range data to CDF files.
