Original data set was  made accessible by Nand Lal at
http://voyager.gsfc.nasa.gov/helios.
This dir. has four data files:
h2_30m_a_flx.txt  01/19/1976 - 06/06/1977 
h2_30m_b_flx.txt  07/01/1977 - 12/31/1978 
h2_30m_c_flx.txt  01/01/1979 - 12/23/1979 
------------------------------
There is a subsetted version of that data set at
dir. "subsetted" at the same level.
The OMNIWeb Plus version of the data can be retrieved and plotted at
