For each of the 49 STEREO-A shocks\nand 46 STEREO-B shocks, the following information is given:\ntime, the ratio of downstream to upstream magnetic field intensity,\nshock normal angle, plasma beta, magnetosonic Mach number, a Y/N flag,\nfor STEREO 32 Hz magnetic field data availability, a comment field \nmainly used to indicate forward vs. reverse shocks.  It is expected \nthat this list, given in both PDF and Excel formats, will be updated \nperiodically.",
