During the course of ten nights of observing (UT 27 April - 6 May 1996), the KPNO Mayall 4m Telescope was used to image the Hubble Deep Field in the near infrared. The IRIM camera employs a 256 x 256 Rockwell NICMOS-3 HgCdTe array, with a scale of approximately 0".6/pixel at the 4m f/15 Cassegrain focus. ... A paper on the HDF/IRIM data (observations, reductions, catalogs and basic analysis) is in preparation, titled "Near Infrared Properties of the Hubble Deep Field" by Dickinson et al. ...
