Purpose: Helper function to access ESA common blocks and return array of indices for mode changes. Notes: When editing this code: -make sure calls to scope_varfetch do not copy unnecessary data (see IDL documentation)

Purpose: Helper function to access SST common block and return array of indices for mode changes. Notes: When editing this code: -make sure calls to scope_varfetch do not copy unnecessary data (see IDL documentation) -make sure not to free pointers copied from the common block

Purpose: Helper function to access raw SST data stored in tplot variables and return array of indices for mode changes. Data loaded with thm_load_sst2 (/sst_cal keyword on higher level routines) is stored in tplot vars instead of the original common block. Notes:

Purpose: Access particle data common blocks to determine where mode changes occure and how many samples are in each configuration. Input: probe: String specifying the spacecraft (e.g. 'a','b',...) datatype: String specifying the type of data (e.g. 'peif') tindex: Array of indices specifying which samples are within the time range. Output: returned value: Array of indices correspinding to the first distribution for each new configuration. n: The total number of samples for each configuration. Usage: indices = thm_part_dist_array_getmodechange(probe='a', datatype='psif', $ tindex=time_index_array, n=n)
