About Stereo data in COHOWEB

STEREO-A and -B data are from the magnetometer of the IMPACT package
and from the PLASTIC plasma detector.  Principal Investigators for these
packages are Janet Luhmann (UCB) and Antoinette Galvin (UNH), 
respectively.  Magnetic field  data were obtained as 10-min averages 
from the UCLA web site at
http://aten.igpp.ucla.edu/forms/stereo/ascii_PLASTIC_10m_new.html,

at GSFC/SPDF by averaging over six 10-min averages.  
Hourly plasma parameter data, including plasma flow direction angles
for STEREO-A but not yet for STEREO B (as of 8/11/2009), 
were obtained from UNH via http://fiji.sr.unh.edu/1dmax_ascii/.
