VLA Test Memoranda

The VLA Test Memoranda discuss technical issues of direct relevance to the practice of observing at the VLA. They differ from the VLA Technical Memoranda in being oriented more towards the user than the engineer. The VLA Scientific Memoranda cover similar ground, but tend to be less technical.

The HTRP is covered by the VLA HTRP Memoranda.
