Some Astronomical Applications of Cross-Correlation Techniques
Cross-correlation techniques have been used for many years to increase the signal-to-noise ratio of a wide variety of analogue and digital data. A large literature describing these methods exists, and many clever applications have been developed (see Fellgett 1953, and esp. Woodward 1955, for a basic mathematical development and applications).

Sandage for his assistance in digitizing the data and evaluating the results, and Dr. G. Neugebauer for valuable suggestions.
