Ms. Frueh is the McDonald Operations staff member responsible for P45. A dual channel photometer is available at any f/13.7 focus (2.1m and 0.9m) or, with lower efficiency, at the f/17.7 focus on the 2.7m telescope. It is operated under computer control and is capable of integration speeds as fast as 1 millisecond.
