------------------------------------------------
Started from 1994, Wind/EPACT/LEMT sensor continuously provided heavy ion intensity data 
having ion energies of a few MeV/nuc. The omindirectional intensity data of 
He, C, O, Ne, Si, and Fe ions are presented in this folder. 
The data are in the text file with the coma-separated format (CSF).
The time resolution of data is one hour.

Each data file includes the omnidirectional intensity data of a given ion species within 
one year coverage. Some explanations about data format are as follows.

The name of data files is: XX_omn_YYYY.txt, where XX and YYYY are the name of ion
species and the year of measurement, respectively. 
Header includes: 
The integer time (Year, Month, Day, Hour and Minute) is the beginning time of measured interval, 
while the float time DOY (Day of year) is the center time of measured interval.
Ion intensity (particles/(cm^2 ster s MeV/nuc)) and error are given for each energy interval.
 When intensity is 0, the one-particle upper limit is given as the intensity error. 
The unit of ion energies is MeV/nuc.
