210 MM Ground-Based Magnetometer Network 1 sec Resolution Data PI: Akimasa Yoshikawa International Center for Space Weather Science and Education, Kyushu University 53, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581, Japan Rules of the Road for 210 MM Data Use: 1. Please contact the Principal Investigator (PI), Dr. Akimasa Yoshikawa, Kyushu University (yoshi at geo.kyushu-u.ac.jp) before using the data at any publications and/or presentations. 2. Please ask the PI about the authorship of the publication/presentation. The PI should be included as a coauthor if the 210MM data are presented in the publication/presentation. The PI may also ask to include some Co-I(s) as coauthors in the publication. 3. Please cite Yumoto et al. (1992) and/or Yumoto et al. (1996) in the publication. The detailed citation is: * Yumoto, K., Y. Tanaka, T. Oguti, K. Shiokawa, Y. Yoshimura, A. Isono, B. J. Fraser, F. W. Menk, J. W. Lynn, M. Seto, and 210 (deg) MM magnetic meridian observation group, Globally coordinated magnetic observations along 210 (deg) magnetic meridian during STEP period: 1. Preliminary results of low-latitude Pc 3's, J. Geomag. Geoelectr., 44, 261-276, 1992. * Yumoto, K., and the 210 (deg) MM Magnetic Observation Group, The STEP 210 (deg) magnetic meridian network project, J. Geomag., Geoelectr., 48, 1297-1309, 1996. 4. These three issues are essentially important for continuation of our widely-deployed 210MM magnetometer chain. If a manuscript with the 210MM data is prepared for publication without considering these rules, PI may ask the journal editor to withdraw the manuscript. 5. For the hdz_1sec variable, channels 1, 2, and 3 correspond to the H, D, and Z components, respectively, in most cases. However, this is not the case with some stations and some periods. For more information, see http://stdb2.stelab.nagoya-u.ac.jp/mm210/error.html. 6. For the data from the stations in the northern hemisphere, [H:+ = northward] [D:+ = eastward] [Z:+ = downward], and for the data from the stations in the southern hemisphere, [H:+ = northward] [D:+ = eastward] [Z:+ = upward]. However, this is not the case with some stations and some periods. For more information, see http://stdb2.stelab.nagoya-u.ac.jp/mm210/error.html.
