NAME: udata_interpolation PURPOSE: Perform the data interpolation for two time-serise data. CALLING SEQUENCE: udata_interpolation, vname1,vname2 INPUT: vname1 = first tplot variable name vname2 = second tplot variable name KEYWORDS: st_time0 = start time of data interpolation ed_time0 = end time of data interpolation reverse = exchange of two data sets If set, the data interplation is performed on the basis of time range of data2. set_interval = set up time interval to interplate the two data sets. If not set, the time interval is determined on the basis of the minimum interval in the two data sets. EXAMPLE: udata_interpolation, tplot1, tplot2 CODE: R. Hamaguchi, 15/01/2013. MODIFICATIONS: A.
