The Cassini Magnetospheric Imaging Instrument (MIMI) Low Energy Magnetospheric Measurement System (LEMMS) uncalibrated data set includes all data collected from the MIMI Data Processing Unit during the entire Cassini mission. The data is provided in an uncalibrated form in conjunction with a PDS MIMI calibration volume COMIMI_0000 which provides specific algorithms for the derivation of calibrated data. Data are presented in a set of tables which are of variable length and use a comma to separate various fields. This data set is intended to be the most comprehensive and complete data set included in the Cassini MIMI LEMMS archive.

A browse data set is included with Key Parameter data that is calibrated using the algorithms provided in the Calibration volume. In addition, a series of images are provided with the KP browse data that displays the KP data which can lead the user to the particular times of interest. This data set should be among the first used by a user of any of the MIMI LEMMS archive as it will lead one to information required to search for more detailed or highly specialized features in the original data. The Key Parameters data set is not intented for direct use, only as a guide to finding points of interest.

This data set comprises low energy charge particle count rate measurements for each energy channel of the LEMMS detector in a regular and high time rate mode. In addition this data set includes LEMMS PULSE HEIGHT ANALYSIS measurement data for a statistically select sample of the particle measurements. The standard product ID's are:

LEMMS Fine Rate Accumulation Data (LFRT0) - low energy charge particle count rate measurements for a select list of channels at a high time resolution.

LEMMS Pulse Height Analysis Data (LPHA0) - Statistically sampled set of discrete particle measurements.

LEMMS Accumulation Rate Data (LACC0) - low energy charge particle count rate measurements

Data products have names of the following form:

LTTTF_YYYYDDD_VVVV.CSV

where

TTT is for data type (ACC or SCI for rates, FRT for fine rates, PHA for pulse height analysis, HDR for Image headers, or IMG for images),

F is an index, starting with 0-9 and continuing to A-Z, that represents the format version of the file.

LTTTF follows the same convention described for directory names above

YYYYDDDHH is the start year and day of year of the data product,

VVVV is a numerical index, starting with 0000, that represents the data version of the file. Data used for testing purposes will set VVVV = 'TEST'
