A) CURRENT SAMPEX DATA AVAILABLE VIA FTP from sampex/combined/ :
   --------------------------------------
There are four types of Level 2 daily files; each file is a composite,
carrying data from all four instruments. HILT and MAST instruments are 
responsible for high resolution data of particles 4 AMU and higher, while 
LICA and PET are designed to cover mainly electrons, protons, and alphas. 
Further details are available in  

     http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=92-038A
 
(1) 30-s fluxes (about 4 MB/day) from several energy channels from each
    instrument; held in subdirectory, 
    sampex/combined/flux_30s_asc. 

(2) Polarcap averaged fluxes (about 600 KB/month) during each polar pass from
    the same channels that populate (1); held in subdirectory,
    sampex/combined/polarcap_avgd_flux.
 
(3) 30-s rates (about 9 MB/day) from all channels of each instrument; held in 
    sampex/combined/rate_30s_asc.

(4) Polarcap averaged rates (3 MB/month) from numerous channels during each
    polar pass; held in subdirectory,
    sampex/combined/polarcap_avgd_flux

The files of (1) and (2) are available in both ASCII (and CDF,elsewhere); only 
the original ASCII is available for the rates. The rate files are not easy to 
interpret; requesters should interact with the PI, Dr. Glenn Mason at the 
Univ. of Maryland (Glenn.Mason@umail.umd.edu).

(B) DOCUMENTATION, FORMAT DESCRIPTIONS, AND SOFTWARE:
    ------------------------------------------------
Documentation and Format Descriptions for Level 2 Data Products: 

The variable names in the data files are "in house" names. The corresponding 
instrument names and energy channels are mapped in the detailed file below.

D) The Project Data Management Plan (PDMP) is also available. It briefly
describes the project, the spacecraft, and the instruments, and gives an
overview of the data and data flow. This is the latest version, but is dated
March 28, 1994, so details of energies, etc. might not be the final values.
