Values of ASY-D, ASY-H, SYM-D, and SYM-H are \navailable from 1981 to within 1-2 months of current date.  All ASY \nand SYM data are currently (as of 12/07/2011) marked as \"provisional.\"  \nAlternative sources of the WDC/Kyoto-generated ASY and SYM indices \ninclude the 1-min OMNI data set at NASA/GSFC/SPDF.",
