† HEP Level-3 CDF開放使用公告
- We, the ERG/HEP team, are pleased to announce that the new HEP Level-3
pitch-angle sorted flux data are now available from the ERG-SC
website. The newly released data have the version number of v01_00.
The data are generated from HEP Level-2 3-D flux data by sorting them
with pitch angle values based on MGF Level-2 8 sec data. In obtaining
average fluxes for pitch angle bins, only electron fluxes for
azimuthal channels of 1, 2, 3, 6, 7, 8, 12, and 13 and for spin
sectors #1, #2, ..., #14 (excluding spin sectors #0 and #15) were used
in order to avoid effects of the imperfect flux normalization in
Level-2 3-D flux data. Consequently, the derived pitch-angle spectra
are equivalent to those that one can calculate using the part_products
routine. Flux values in the Level-3 data have been averaged for 8
satellite spins (~ 64 sec) to get smooth spectra over pitch angle.
The Level-3 data are going to be made publicly available with a 1-year latency.
For SPEDAS users, the latest version of erg_load_hep.pro bundled in
the ERG-SC plug-in for SPEDAS can be used to load Level-3 data. Copied
below are some sample commands.

HEP Level-3 data archived in the CDF format are available online from
the ERG-SC data repository at:
https://ergsc.isee.nagoya-u.ac.jp/data/ergsc/satellite/erg/hep/l3/pa/
The latest update and information on the instrument and data can also
be found in the wiki page at:
https://ergsc.isee.nagoya-u.ac.jp/mw/index.php/ErgSat/Hep
The ERG project asks all data users to show which version of data were
used for his/her studies. This information should be included in, for
example, the acknowledgment section of scientific papers in which ERG
(Arase) satellite data are used.
The project also asks you to read carefully and follow the rules of
the road (RoR) when you use the data for your own research. The latest
RoR for the HEP and MGF data are copied at the end of this
announcement. As the RoR reads, please contact the HEP and MGF teams
(erg_hep_info [at] isee.nagoya-u.ac.jp, erg_mgf_info [at]
isee.nagoya-u.ac.jp) before using the data for any publications and
presentations.

Rules of the Road for the users of the products from the ERG/Arase Project
1. Users of all level of scientific products from the ERG/Arase
project should contact instrument PI team(s), Project Manager (PM),
and Project Scientist (PS) before using the data for any presentation
and publication. PI(s) / PM (Iku Shinohara, iku at stp.isas.jaxa.jp) /
PS (Yoshizumi Miyoshi, miyoshi at isee.nagoya-u.ac.jp) may suggest
potential coauthor(s) from the ERG/Arase project side for the
presentation and publication. Some necessary articles suggested by the
PI(s) should be cited.
2. Users should always use the latest version of data files in CDF
provided from the ERG science center for their data analysis,
presentation and publications. Redistribution of the data files is
strictly prohibited.
3. Users should send presentation materials and papers including
ERG/Arase data to instrument PI team(s), PM, and PS enough before
presentation and paper submission, so that sufficient time is
available for those responsible for the data to check if the data are
properly processed/used and to get necessary comments back to the data
users.
4. Publications that use ERG/Arase satellite data should cite the
project overview paper (Miyoshi et al., Earth Planets Space,
DOI:10.1186/s40623-018-0862-0, 2018a) and include the following text in
the paper acknowledgements:
"Science data of the ERG (Arase) satellite were obtained from the ERG
Science Center operated by ISAS/JAXA and ISEE/Nagoya University
(https://ergsc.isee.nagoya-u.ac.jp/index.shtml.en, Miyoshi et al., 2018b).
The present study analyzed MGF-L2 v01_01 data, HEP-L2 v03_01 data,
MEP-e-L2 v01_01 data, and Orbit L3 v02 data"

Rules of the Road of HEP Level 2 data
For details of the instrument, please refer to the following article:
Mitani, T., et al. (2018), High-energy electron experiments (HEP) aboard
the ERG (Arase) satellite, Earth, Planets and Space, 70:77,
doi:10.1186/s40623-018-0853-1.
The users should be aware that the current version of Level-2 data may
still contain contamination to flux values due to penetration of higher
energy electrons and protons. The users should analyze data carefully not
only for quantitative studies but also qualitative examination.It is
highly recommended to establish contact and work together with the PI
team from the early stage of the user's study.
Level-2 data can be updated in future if necessary. Please make sure to
use the latest version of data for the analyses.
Further information on the data can be found at the following wiki page:
https://ergsc.isee.nagoya-u.ac.jp/mw/index.php/ErgSat/Hep
Questions, comments, and any feedback relevant to the data should be
directed to the HEP team (E-mail: erg_hep_info at isee.nagoya-u.ac.jp).
Rules of the Road of Level-2 data (MGF)
The MGF Level-2 data should be used based on a full understanding of
the measurement limit.
Please refer to and cite the following article: Matsuoka, A. et al.
(2018), The ARASE (ERG) magnetic field investigation, Earth, Planets
and Space, doi:10.1186/s40623-018-0800-1, if you use the MGF data for
your research.
Further information on the data can be found at the following wiki
page: https://ergsc.isee.nagoya-u.ac.jp/mw/index.php/ErgSat/Mgf/
Questions, comments, and any feedback relevant to the data should be
directed to the MGF team (PI: Ayako Matsuoka) (contact: erg_mgf_info
at isee.nagoya-u.ac.jp).
