The following table lists zero points for NICI in several filters. A zero point is defined as the magnitude of an object that would yield 1 ADU/sec at an airmass of 1. They depend on instrument and telescope transmittances as well as detector electronics.

All values here were computed from observations of the near-infrared standard S372-S on 2008 Jan 31, with the H50/50 beamsplitter.
