;+ ;NAME: barrel_load_ephm ;DESCRIPTION: CDF-to-TDAS import routine for BARREL ephemeris/gps (EPHM) data products ; ;REQUIRED INPUTS: ; none ; ;KEYWORD ARGUMENTS (OPTIONAL): ; PROBE: String [array] of BARREL identifiers (e.g., '1A', '1B'). ; Default is 'all' (i.e., all available payloads). May also be ; a single string delimited by spaces (e.g., '1A 1B'). ; DATATYPE: String [array] of BARREL datatype identifiers (e.g. 'EPHM'). ; TRANGE: Time range for tplot (2 element array). Loads data in whole-day ; chunks, and will prompt user if not specified. ; LEVEL: String [array] of data level code (e.g. 'l1', 'l2'). ; VERSION: String specifying data revision number (e.g. 'v01', 'v02'). ; /VERBOSE: ; CDF_DATA: (not implemented) ; /GET_SUPPORT_DATA: Load support_data variables as well as data variables. ; TPLOTNAMES: (passed through to 'cdf2tplot' and 'cdf_info_to_tplot') ; MAKE_MULTI_TPLOTVAR: (not implemented) ; VARFORMAT: String (passed through to 'cdf2tplot'). ; /VALID_NAMES: (not implemented) ; FILES: (not implemented) ; ; (FILE_RETRIEVE KEYWORDS-- descriptions borrowed from file_retrieve.pro) ; /DOWNLOADONLY: ; Set to 1 to only download files but not load files into memory. ; /NO_SERVER: Set to 1 to prevent any contact with a remote server. ; /NO_DOWNLOAD: Identical to NO_SERVER keyword. Obsolete, but retained for backward compatibility ; /NO_UPDATE: Set to 1 to prevent contact to server if local file already exists. (this is similar to no_clobber) ; /NO_CLOBBER: Set to 1 to prevent existing files from being overwritten. (A warning message will be displayed if remote server has) ; ;OUTPUTS: ; none ; ;STATUS: ; ;TO BE ADDED: n/a ; ;EXAMPLE: ; ;REVISION HISTORY: ;Version 0.93e KBY 08/28/2013 explicit support for 'support_data' (e.g., FrameGroup); ; rename from "barrel_load_gps" to "barrel_load_ephm"; ; support for noting VALID_MIN and VALID_MAX values ;Version 0.93d KBY 08/23/2013 quality indicator ("Q") renamed "Quality"; ; take unit labels from CDF metadata; update documentation. ;Version 0.93c KBY 08/23/2013 BARREL payload identifiers shortened to alphanumeric build ; order only (e.g., '1A', '1B'), following change to CDF naming convention ;Version 0.93a KBY 08/16/2013 CDF variable "GPS_Time" deprecated (removed ; from v02 CDF files); specify default value for "unit" ;Version 0.92 KBY 06/04/2013 introduced VERSION keyword ;Version 0.91c KBY 05/31/2013 handling of ISTP fill values ;Version 0.91b KBY 05/31/2013 check for and delete existing variables of same name ;Version 0.91a KBY 05/28/2013 updated to reflect namechange from 'gps' to 'ephm'; ; added file_retrieve keywords (no_download/update/clobber) ;Version 0.90a KBY 04/22/2013 re-factoring of generic load actions; update CDF compatibility ;Version 0.83 KBY 11/28/2012 initial beta release ;Version 0.82 KBY 11/27/2012 debugging with updated CDF definitions ;Version 0.81 KBY 11/21/2012 new CDF definitions;
