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/. Name of parameters in each of ASCII records ( 15 words): Year DOY Hour Radial Distance, AU HGI Lat. of the S/C HGI Long. of the S/C IMF BR, nT (RTN) IMF BT, nT (RTN) IMF BN, nT (RTN) IMF B Scalar, nT SW Plasma Speed, km/s SW Lat. Angle RTN, deg. SW Long. Angle RTN, deg. SW Plasma Density, N/cm^3 SW Plasma Temperature, K ------------------------- Note that for missing data, fill values consisting of a blank followed by 9's which together constitute the format are used ------------------------------- For browse and retrieval that data see: http://omniweb.gsfc.nasa.gov/coho/ ------------------------------------------------------------ Related data and directories: SPDF Data and Orbits Services ------------------------------------------------------------------- SPDF Contact: Natalia Papitashvili ------------------------------------------------------------- Please acknowledge NASA's Space Physics Data Facility and and relevant scientists identified above for data usage. -------------------------------------------------------- Authorizing NASA Official: Dr. R.E.
