Abstract
A new two-color system for photoelectric photometry has been devised to aid
interpretation of near-infrared photographs taken on the IV-N emulsion.
The system should also lend itself to applications using silicon diode
detectors. This paper describes the instrumentation, establishement of
standard stars, and transformations to other systems. In addition,
photoelectric sequences are given for some fields near the galactic plane.
