# Routine Descriptions

## YYY_LOAD_DATA

[Next Routine] [List of Routines]

    NAME:
      yyy_load_data
               This routine is a template for loading data into tplot variables and
               must be replaced with mission specific load routines.
               For this example fake data is generated using dindgen.
               Typically SPEDAS load routines load data into tplot variables. The
               SPEDAS load routines uses http copies to retrieve the cdf file. The
               file is then read and data placed into tplot variables.

    KEYWORDS (commonly used by other load routines):
      PROBE    = Probe name. The default is 'all', i.e., load all available probes.
                 This can be an array of strings, e.g., ['a', 'b'] or a
                 single string delimited by spaces, e.g., 'a b'
      DATATYPE = The type of data to be loaded, can be an array of strings
                 or single string separate by spaces.  The default is '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    = Level is not used in this example but is common to many mission.
                 Please refer to the equivalent GOES, WIND, SPEDAS or ACE load
                 routines for examples.

    EXAMPLE:
       yyy_load_data,probe='x'

    NOTES:
       Each mission is different and you may not need all of the keywords listed below
       or you may need more to adequately specify instrument, probe, and data types.

## YYY_UI_LOAD_DATA

[Previous Routine] [Next Routine] [List of Routines]

    NAME:
      yyy_ui_load_data

    PURPOSE:
      This routine provides examples for building load data panel widgets and
      handles the widget events it produces. This is a template only and creates
      basic widgets that are common to most missions.
      Each mission is different. Some widgets may need to be added to fully specify
      the data set to be loaded or some may not be needed.

## YYY_UI_LOAD_DATA_IMPORT

[Previous Routine] [List of Routines]

    NAME:
      yyy_ui_load_data_import

    PURPOSE:
      This routine provides an example for loading data into the GUI from the load
      data panel. The purpose of this routine is to provide a wrapper around the
      actual load data procedure (which is mission specific). This routine handles
      all the 'administrative' work of validating times, checking if data exists,
      and adding the data to the GUI's loadedData object. The loadedData object
      loads and tracks all data that is available to the GUI.

     INPUT:
      loadStruc - this structure contains all the mission specific information that
                  is required by the procedure that loads the data.
                  For purposes of demonstration, this rouine uses the following
                  parameters:
                  probe - character string or an array of strings which contain
                          the name of the probe. Examples include, 'a', 'b', 'c',
                          'd', 'e', or 'g' (for SPEDAS). This routine uses 'y'.
                  instrument - character string (or array) containing the name of
                               the instrument such as 'fgm', 'esa', or in this
                               case 'inst1'
                  datatype - character string or an array of stringscontaining the
                             type of data to be loaded. Examples include 'pos',
                             'fge', or 'peir' for SPEDAS. This example simply uses
                             'type1'
                  time range - an array of 2 character strings containing the
                               start and stop times of the data to be loaded.
                               ['2007-03-23/00:00:00', '2007-03-24/00:00:00']
      loadedData - the loaded data object contains information on all variables
                   currently loaded in the gui. This object is used by many other
                   panels to display the variables that are available to the GUI.
                   Whenever new data is imported to the GUI this object must be
                   updated.
      statusBar - the status bar object used to display textual information
                  for the user and is located at the bottom of the load windows.
                  This object can be used to inform the user of successful
                  executions, warnings, and/or errors.
      historyWin - the history window object displays all messages generated
                   during this session.
      parent_widget_id - the widget ID of the parent. This ID is needed for
                         appropriate layering and modality of popups

      KEYWORDS (OPTIONAL):
      replay - set this flag to replay previous dproc operations
      overwrite - this flag allows the replay of user overwrites
