PROCEDURE: iug_load_lfrto PURPOSE: To load the Low Frequency Radio Transmitter Observation data from the Tohoku University site KEYWORDS: site = Observatory name, example, iug_load_lfrto, site='ath', the default is 'ath', athabasca station. This can be an array of strings, e.g., ['ath', 'nal'] or a single string delimited by spaces, e.g., 'ath nal'. Sites: ath nal trans = Transmitter code, example, iug_load_lfrto, trans='wwvb', the default is 'all', i.e., load all available transmitter. This can be an array of strings, e.g., ['wwvb', 'ndk'] or a single string delimited by spaces, e.g., 'wwvb ndk'. Transmitter: wwvb ndk nlk npm nau nrk nwc msf dcf parameter = Parameter name. 'power' or 'pow' for amplitude. 'phase' or 'pha' for phase. datatype = Time resolution. '30sec' or '30s' for 30 sec. The default is '30sec'. /downloadonly, if set, then only download the data, do not load it into variables. /no_download: use only files which are online locally. /verbose : set to output some useful info trange = (Optional) Time range of interest (2 element array). EXAMPLE: iug_load_lfrto, site='ath', datatype='30sec', $ trange=['2011-05-29/00:00:00','2011-05-30/00:00:00'] NOTE: See the rules of the road.
