About STEREO ASCII merged data
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/level2_plasma_and_magnetic_field.html,
courtesy of C.T. Russell. COHOWeb's magnetic field hourly averages
were created at GSFC/SPDF by averaging over the six 10-min averages
falling within each hour. Hourly plasma parameter data,
were obtained from UNH via http://fiji.sr.unh.edu/1dmax_ascii/.
