TWIST Technical Notes

When you're writing a Technical Note, please check with the Technotes Maintainer (currently Robert MacDonald) to get a Technote number (to prevent collisions). It would be helpful if that number shows up on your title page or something.

Technical Notes are submitted to the Forum. When posting there, please include the following:

• A subject line in the form TN-## With a Descriptive Title
• A brief abstract in the text of the email
• Attachments (please gzip these if possible!):
  • A full .ps or .pdf file with the figures embedded (no need to gzip the pdf, of course)
  • A .tex copy of the text (or whatever source file you used to make the .ps or .pdf)
  • Individual .eps files with each figure (or better yet, a .tar file of these files)
