IVS Publications and Presentations

IVS Memoranda

Purpose. The IVS Memoranda represent a fast way to document IVS related developments. Everyone can request the posting of a memo. There is no formal review process or editing, but we reserve the right of declining a posting.

Submission. To request a memo posting send your material in PDF, DOC or WP format to Dirk Behrend. The preferred format is PDF as this is the format being used for the final posting. A titlepage will be prepended to the body of the text at the Coordinating Center, where the contents of the titlepage are: memo number (including version number), date, author(s), and title.

The date, author(s) and title information needs to be provided with the initial submission. If an updated version of an already existing memo is submitted, also the memo number needs to be given.

Current list. Please click on the title to view the memo you are interested in.
