For Hi-Ions, the Rate Boxes are regions in the TOF-Energy plane (see Figure 11-6 [in the ICD]). The precise specification of the rate boxes is complex and this is why we include rate box classifications in the Level 2 PHA data. However, we also provide the file RATEBOXDEFINITIONPLANES.FIT [this file] in the CALIB/ directory of PDS data sets. Through the Jupiter mission phase and into the Pluto Cruise mission phase, PEPSSI has had three sets of Rate Box definitions. There are separate rate box definitions for Normal and Diagnostic mode. The RateBoxDefinitionPlanes.fit file contains 6 extenstions (3 sets x 2 modes). The Rate Box classification data is presented as an image containing the Rate Box id number (0-18) in the Time of Flight (TOF) vs Energy plane. TOF and Energy are presented in raw analog to digital units (ADUs). Thus, TOF ranges from 0-2047 and Energy from 0-1023. The Rate Box classification of any event can be determined by looking up the corresponding pixel in the classification image. In diagnostic mode, Energy-only detections have a fill value of 2047 for TOF, and the Rate Box classification image assumes these fill values. The time range for each set is given in the header of the respective HDU. The ranges are: +-------+----------------------------+ | Set 0 | Before 2006-7-7 | +-------+----------------------------+ + Set 1 | 2007-7-7 through 2007-5-24 | +-------+----------------------------+ + Set 2 | After 2007-5-24 | +-------+----------------------------+ Details ======= Each IMAGE OBJECT is a 3-dimensional representation of PEPSSI Rate Box Definition for one of those sets above. PEPSSI event measurements comprise an Energy measurement and a Time-Of-Flight (TOF) measurement. The combined (TOF,Energy) pair of each measurements represents a position on the TOF vs. Energy plane. Each position on that plane corresponds to one of nineteen rate boxes, as displayed in Figure 11-6 of the SOC_INST_ICD document. The LINE_SAMPLES axis in each IMAGE represents the Energy ADU (Analog- Digital Units; raw energy data number) of a PEPSSI raw measurement, LINE_SAMPLES positions 1 through 1024 corresponds to Energy ADU measurements of 0 through 1023. The LINES axis in each IMAGE represents the TOF ADU of a PEPSSI raw measurement, LINES positions 1 through 2048 corresponds to TOF ADU measurements of 0 through 2047. The value of each location in the IMAGE OBJECT is the Rate Box Index for that location's Energy and TOF ADU values.
