A two-color photometric system for the near infrared A new two-color system for photoelectic photometry has been devised toaid interpretation of near-infrared photographs taken on the IV-Nemulsion. The system should also lend itself to applications usingsilicon diode detectors. This paper describes the instrumentation,establishment of standard stars, and transformation to other systems. Inaddition, photoelectric sequences are given for some fields near thegalactic plane.
