Procedure: THM_LOAD_ASK Purpose: Loads THEMIS All Sky Keograms keywords: site = Observatory name, example, thm_load_gmag, site = 'fykn', the default is 'all', i.e., load all available stations . This can be an array of strings, e.g., ['fykn', 'gako'] or a single string delimited by spaces, e.g., 'fykn gako' datatype = request 'ast' or 'asf', default is 'asf', can also be 'all'. TRANGE= (Optional) Time range of interest (2 element array), if this is not set, the default is to prompt the user. Note that if the input time range is not a full day, a full day's data is loaded level = the level of the data, the default is 'l2', or level-2 data. A string (e.g., 'l2') or an integer can be used. 'all' can be passed in also, to get all levels. /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. relpathnames_all: named variable in which to return all files that are required for specified timespan, probe, datatype, and level. If present, no files will be downloaded, and no data will be loaded. /valid_names, if set, then this will return the valid site, datatype and/or level options in named variables, for example, thm_load_gmag, site = xxx, /valid_names will return the array of valid sites in the variable xxx get_support_data = does nothing. present only for consistency with other load routines Example: thg_load_ask Notes: This routine is (should be) platform independent. $LastChangedBy: pcruce $ $LastChangedDate: 2012-06-29 15:55:05 -0700 (Fri, 29 Jun 2012) $ $LastChangedRevision: Added valid_names output option$ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/themis/ground/thm_load_ask.pro $
