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 to be copied by anonymous ftp. If you have a large or complex data request, you may prefer you to visit the YDAC in order to gather the data yourself.
Please note that all Yohkoh data requests are subject to the YDAC Data Policy - if you are collaborating with someone, please tell us.
Everyone using Yohkoh data provided by the YDAC is encouraged to register their interest in analysis projects through the Team Bulletin Board; 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.
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: firstname.lastname@example.org).
Anyone within the United States should contact the Solar Data Analysis Center, the SDAC (e-mail address: email@example.com).
