                This file contains Cassini Magnetospheric Imaging Instrument (MIMI) Charge Energy Mass Spectrometer 
                (CHEMS) 20-day mass per charge versus time of detection (UT) spectrograms. The page shows the number of 
                triples coincidence PHA events in one hour intervals and 5% mass per charge bins.

                Plots have one-hour resolution and are based on CHEMS PHA data. The
                bottom axis is time covering a 20 day interval. Also
                given is the position of the Cassini spacecraft in SZS (Saturn
                equatorial) coordinates. The coordinates are radial distance from the
                center of Saturn in Saturn radii, latitude in degrees, and local time
                in decimal hours (sunward = 12.0, anti-sunward = 0.0).
                                                                  
                The data is from DPPS steps 24-31 (83.4 - 220.2 keV/e).
                                                                  
                The top panel shows data from all three CHEMS telescopes combined (4
                degrees x 159 degrees Field of View (FOV)), while the lower three
                panels separate data by telescope (4 degrees x 53 degrees FOV each).
                                                                                    
                The range of possible mass per charge values depends on the CHEMS E/Q
                range. The range is 0.7 - 80 amu/e for the complete 2.8-220 keV/e.
