Cassini MIMI<br>Magnetospheric IMaging
    Instrument




MIMI uncalibrated data is available at the Planetary Data System Plasma Interactions Node (PPI). http://ppi.pds.nasa.gov/
The data files are avaliable individually by navigating the menus starting at the PPI node but we find using the following link or the ones in the following table makes it easier to obtain the files. http:/ppi.pds.nasa.gov/archive1

The data is organized into the following mission phases.

LEMMSAccumulation RatesLEMMS_ACCUMULATION_RATES
ACC
Tables of counts for various particle channels.
Fine Accumulation RatesLEMMS_FINE_ACCUMULATION_RATES
FRT
Tables of counts for various particle channels. The fine rate data are comprised of a small subset of the channels measured at a finer time cadence, typically eight times more frequently than the normal accumulator rates
Pulse Height AnalysisLEMMS_PULSE_HEIGHT_ANALYSIS
PHA
The LEMMS PHA data is a set of 64 closely spaced energy channels covering 12 to 833 keV for protons, 39 to 2295 keV for F detector electrons and 6.7 to 451 keV for E channel electrons.
CHEMSBasic and Science RatesCHEMS_SCIENCE_RATES
SCI
The Science Accumulator Rates contain counts for all of the science channels.
Accumulation RatesCHEMS_ACCUMULATION_RATES
ACC
The Accumulation Rates contain diagnostic counts i.e., all valid triggers, or all time of flight (TOF) stop events.
Pulse Height AnalysisCHEMS_PULSE_HEIGHT_ANALYSIS
PHA
CHEMS PHA data is more typical than LEMMS PHA in that it provides a list of individually detected particles, with specific detection parameters for each event, including TOF, energy deposited in the SSD, and telescope number.
INCAImagesINCA_IMAGES
IMG
INCA images are relatively low resolution (up to 64 by 64 pixels), large field of view (90 by 120) pictures of neutrals, similar to any remote sensing imager. Note however, that INCA has an ion mode in which neutral counts are drowned by incident ions. These ion images offer very good pitch angle distributions of in-situ particle distributions.
Accumulation RatesINCA_ACCUMULATION_RATES
ACC
INCA rate channel data consists of diagnostic counters for assessing instrument performance and health.
Pulse Height AnalysisINCA_PULSE_HEIGHT_ANALYSIS
PHA
INCA PHA data is similar in concept to the CHEMS PHA data, providing event characteristics for a subset of incident particles, either ions or neutrals.
