ENA images are collected when the voltage on the INCA collimator is high, typically 4kV. This excludes ions with E/q values less than ~180 to 200keV/q. The value displayed is the log of the image intensity in counts/(centimeters squared*steradian*seconds*keV). Many of the movies were created before we adjusted the energy ranges for older data. Movies for the time range 2004 - 2009 are labeled with the wrong energy range so the following energy range is the corrected energy range. The energy range for the high spatial resolution hydrogen image is (TOF id is the value in the TOF column in the angle average files) TOF id 0 = 55-90 keV The color bar limits are set to a common minimum and maximum value over the entire movie, chosen to bring out the salient features over the time covered. These values typically change from one movie to the next, based on activity levels and orbital position. Each original image N x N pixel image (where N is usually 32 or 64) was transformed into the Saturn frame, a frame dynamically defined as follows. The primary axis is the CASSINI spacecraft-to-Saturn vector and is labeled X. The secondary (Z) axis is the Z axis of the IAU_SATURN frame (the Saturn spin axis). The Y-axis completes the right-handed system. The skymap display is defined to display every frame with the Z axis up, X axis points into the page, the Y axis to the left. So in the skymap projection, into the page is the spacecraft to Saturn vector, Z axis (or up) is the Saturn spin axis. Occasionally, for Titan flybys, the image was transformed into the Titan frame, a frame dynamically defined as follows. The primary axis is the CASSINI spacecraft-to-Titan vector and is labeled X. The secondary (Z) axis is the Z axis of the IAU_TITAN frame (the Titan spin axis). The Y-axis completes the right-handed system. Typically, though not always, the orbit of Titan, Dione and Rhea (dotted line), Titan center (dot), and the axis for Saturn equatorial system frame (white, centered at Saturn) are displayed. The definition of the Saturn equatorial system frame has the primary axis, labeled Z, parallel to the Saturn spin axis. The Y-axis is then defined as the cross product of this vector with the Saturn-Sun vector. The X-axis completes the right-handed system and is directed roughly sunward, lying in the plane containing both Z and the Saturn-sun vector. The pink axis (when present) is the Saturn Kilometric Radiation frame. Due to the work of the RPWS team we now have several Saturn Kilometric Radiation frames available for use.[1] If the Saturn Axis frame is marked SKR on the movie, then the Saturn Kilometric Radiation frame uses SLS3. If the Saturn Axis frame is marked SKRN, or SKRS, then the frame uses SLS4 north or SLS4 south respectively. The Z-axis is coincident with the instantaneous body rotation vector (spin axis) of Saturn. At the bottom of the page, the Rs=radius to Saturn, Lat=latitude in IAU_SATURN frame, LT=Saturn Local Time, L=L value,local time of Cassini relative to Saturn, Lon skr-wl= Longitude of Cassini in the Saturn Kilometric Radiation (western longitude) frame. The values may be missing during some frames in the movie if there was no Cassini pointing information available.
