This subdirectory contains the catalog object files for the entire
volume. The following files are included in the catalog subdirectory.

CATINFO.TXT: Description of the contents of this directory (this file).

EPPSEPSDATASET.CAT: Describes the general content of the EPS
uncalibrated data set and includes information about the duration
of the mission and the person or group responsible for producing
the data.

EPPSFIPSDATASET.CAT: Describes the general content of the FIPS
uncalibrated data set and includes information about the duration
of the mission and the person or group responsible for producing
the data.

EPPSEPSDATASET_CDR.CAT: Describes the general content of the EPS
calibrated data set and includes information about the duration
of the mission and the person or group responsible for producing
the data.

EPPSFIPSDATASET_CDR.CAT: Describes the general content of the FIPS
calibrated data set and includes information about the duration
of the mission and the person or group responsible for producing
the data.

NOTE: The DATASET.CAT catalog has been replicated as four seperate
catalog files, EPPSEPSDATASET.CAT, EPPSFIPSDATASET.CAT,
EPPSEPSDATASET_CDR.CAT, and EPPSFIPSDATASET_CDR.CAT. The files
EPPSEPSDATASET.CAT and EPPSFIPSDATASET.CAT are essentially identical,
as are the files EPPSEPSDATASET_CDR.CAT and EPPSFIPSDATASET_CDR.CAT,
but each has a different data set id, one for the EPS detector and
one for the FIPS detector.

INSTRUMENT.CAT: Describes physical attributes of the EPPS instrument and
provides relevant references to published literature.

INSTHOST.CAT: Describes the MESSENGER spacecraft.

MISSION.CAT: Describes the scientific goals and objectives of the
MESSENGER program.

PERSON.CAT: Lists and provides contact information for the people
involved in the MESSENGER mission, including those involved with EPPS.

REF.CAT: Provides references to scientific papers and other publications
of interest to those using the data, both for EPPS and the mission as a
whole.
