0readme.txt [To go in sampex/combined/polarcap_avgd_rate directory in RAID] This directory carries the polarcap-averaged rates from all energy/mass channels from each of the four instruments; data from each polarcap pass are aggregated as monthly files. "Polarcap" is defined as the region poleward of the geomagnetic latitudes +/- 70 deg. Typically there will be about 26 polarcap passages/day. The format, and other documentation are available from FTP sites listed in the 0readme.txt in sampex/combined directory. Caution: as stated in that 0readme.txt, the Principal Investigator should be contacted by those who wish to convert these rates into fluxes.
