VLA Scientific Memoranda

The VLA Scientific Memoranda discuss instrumental, algorithmic, and other issues which directly affect the science done with the VLA. They are distinguished from the VLA Test Memoranda in being further removed from the instrumentation, covering somewhat broader issues, and concentrating more often on data processing techniques.

For more information on VLA Scientific memoranda, and for copies of memos not available on-line, contact Lori Appel at 505-835-7310, or via e-mail at lappel@nrao.edu
