Abstract
The SAMM automatic measuring machine acquired in 1966 was built for the specific purpose of measuring parallax plates obtained with the 61-inch astrometric reflector located at the Observatory’s Flagstaff Station in Flagstaff, Arizona. More than 50,000 plates have been measured with this machine.
The STARSCAN, acquired in 1974, is similar in principle to the first machine but reflects certain improvements in solid state circuitry, minicomputer technology, and data handling.
