NAME: thm_fftfbk_overplot PURPOSE: Creates overview plots of FBK and FFT (in fast-survey FFF mode) for all probes. Two plots are created, one for the "inner probes" (a, d, e) and one for the "outer probes" (b, c). There are four quantities for each probe, two FBK and two FFF. CALLING SEQUENCE: thm_fftfbk_overplot, date=date,device = device, $ directory = directory, makepng = makepng INPUT: date = the date for the plots, e.g., '2012-12-21' in any tplottable format OUTPUT: none explicit, plots are generated KEYWORDS: DEVICE: sets the device (x or z) (default is x) MAKEPNG: keyword to generate 5 png files DIRECTORY: sets the directory where the above pngs are placed (default is './') $LastChangedBy: aaflores $ $LastChangedDate: 2012-01-26 16:41:44 -0800 (Thu, 26 Jan 2012) $ $LastChangedRevision: 9622 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/themis/common/thm_fftfbk_overplot.pro $
