A Simultaneous Two Channel Photometric System
A photometric system capable of simultaneous dual channel operation has been developed. The photometer head unit permits simultaneous observation of two stars using suitable optics and mechanically coupled photomultiplier systems. The instrumentation and control system is centred around a DEC micro/PDP-11 computer and incorporates general purpose hardware and software developed specifically for the system.
