Access to the YDAC
Users who wish to analyse Yohkoh data can gain access to the
Yohkoh Data Archive Centre through the Internet (IP Address
ydac.mssl.ucl.ac.uk). For security reasons, we prefer all
users to have their own accounts; accounts will be allocated to
approved users on request after the completion of a simple
form. A
PostScript Version of the form is available.
Note:
Researchers in Europe who would like to have access to
Yohkoh data that are in the public domain will probably prefer to
contact this data centre, the YDAC (e-mail address:
ydac@mssl.ucl.ac.uk).
Anyone within the United States should contact the Solar
Data Analysis Center, the SDAC (e-mail address:
yohkoh_sdac@solar.stanford.edu).
YDAC Data Requests
If you are able to analyse Yohkoh data at your home institution
and just need the data, please send your data request to
ydac@mssl.ucl.ac.uk. Please specify the dates and times
required, together with which instruments files you need. The data will be
prepared and you will be informed by e-mail when they are available. If
you have a large or complex data request, we would prefer you to visit the
YDAC in order to gather the data yourself.
Please note that all data requests are subject to the YDAC Data
Policy - if you are collaborating with someone, please tell us.
YDAC Data Policy
The YDAC follows the agreed data policy of the Yohkoh Team.
All YDAC users are allowed full access to any data more than twelve
months old; this data is in the public domain. Those researchers who have
links with the Yohkoh Team on specific projects can access more recent data
if needed. Everyone using YDAC is encouraged to register their interest in
analysis projects through the Team Bulletin Board (TBB), this is the way
Yohkoh Team members keep in touch. If necessary, the YDAC can help users
establish collaborations with appropriate members of the Yohkoh Team.
