PROCEDURE: thigh_pass_filter, varname, dt, newname = newname PURPOSE: Uses high_pass_filter to calculate a running average of the input data and store the data with the running average subtracted in an output tplot variable. INPUT: varname = variable passed to get_data, example - thg_mag_ccnv dt = the averaging time (in seconds) KEYWORDS: newname: set output variable name no_time_interp: Set to save memory by preventing interpolation of time array when smoothing data before subtraction. This option will probably be significantly slower. double: Set so operation is performed at double precision regardless of input type. (If input data is double calculation is always done in double precision) interp_resolution = If time interpolation is being used, set this option to control the number of seconds between interpolated samples. The default is to use the value of the smallest separation between samples. Any number higher than this will sacrifice output resolution to save memory. (NOTE: This option will not be applied if no interpolation is being performed because either (1) no_time_interp is set or (2) the sample rate of the data is constant) interactive_warning = pops up a message box if there are memory problems and asks the user if they would like to continue warning_result = assign a named variable to this keyword to determine the result of the computation display_object = Object reference to be passed to dprint for output.
