A1sxx_YYYYMMDD.TXT File 	 

Description:

Hourly output of deduced bulk flow velocity and first-order anisotropy data of H, He, O, and Fe ions. 

Data format is tab-delimited text file, whose 8-digit name is yyyymmdd that gives the 
year, month, and day of the launch time of the primary coronal mass ejection (CME) 
for given solar energetic particle (SEP) event. In addition, two digits xx = im (go) when the 
proton energy spectrum is calculated from IMP-8 (GOES) data. 

The following symbols are used to represent different ions.
i = 1 	pl: 	2.5-4 MeV H ions
i = 2 	al: 	2.5-5 MeV/n He ions
i = 3 	ah: 	5-8 MeV/n He ions
i = 4  	ol: 	2.5-5 MeV/n O ions
i = 5 	fl: 	2.5-5 MeV/n Fe ions

Variable Notes:

Year (I4), Month (I2), Day (I2), Hour (I2), Doy (F11.6), and Day (F11.6)
	Doy: Day of Year; 
	Day: Day of Month with Day < 0 (> 31) indicating that the day is in the last (next) month
