Each file contains one day of 6-second averages.

The file name is: hNYYDDD.asc, with N the Helios number (1 or 2),
YY the year (last two digits), and DDD the day of year (1 = January 1st).

The format, for each average, is:   (1X,I1,I2,I3,4I2,3F7.2,4F6.2).

Magnetic field components are in solar-ecliptic (SE) spacecraft-centered 
coordinates.
