Near-Infrared Camera and Multi-Object Spectrometer Observations of the Hubble Deep Field: Observations, Data Reduction, and Galaxy Photometry
Abstract
This paper presents data obtained during the NICMOS Guaranteed Time Observations of a portion of the Hubble Deep Field. The data are in a catalog format similar to the publication of the original WFPC2 Hubble Deep Field program (Williams et al.). The catalog contains 342 objects in a 49farcs1 × 48farcs4 subfield of the total observed field, 235 of which are considered coincident with objects in the WFPC2 catalog. The 3 σ signal-to-noise ratio level is at an aperture AB magnitude of approximately 28.8 at 1.6 μm. The catalog sources, listed in order of right ascension, are selected to satisfy a limiting signal-to-noise ratio criterion of greater than or equal to 2.5. This introduces a few false detections into the catalog, and users should take careful note of the completeness and reliability levels for the catalog discussed in §§ 9 and 10. The catalog also contains a test parameter indicating the results of half-catalog tests and the degree of coincidence with the original WFPC2 catalog.

© 1999. The American Astronomical Society. Received 1998 August 24; accepted 1998 October 1. Many people contributed to the NICMOS observations of the Hubble Deep Field. The entire NICMOS Instrument Definition Team contributed to the success of NICMOS and participated in the decision to allocate a large fraction of the team's guaranteed time to this effort. We wish to thank Mark Dickinson for help with the KFOCAS reduction techniques and Andy Fruchter for his aid in implementing the Drizzle image procedure. Andy Lubenow spent many hours refining our observation plan to handle the single guide star acquisition. Chris Conner and the Lockheed MOSES group went to extraordinary efforts to keep the gyro biases updated to ensure good pointing under single guide star tracking. Zolt Levay provided invaluable assistance in the preparation of the images for publication and E. Bertin provided the SExtractor software and quick response to inquiries. The schedulers at STScI diligently worked to minimize the impact of SAA crossings. L. S.-L. thanks Lin Yan and Patrick McCarthy and R. J. W. thanks David Koo for very useful discussions on incompleteness testing and galaxy surveys. This work was supported by NASA grant NAG 5-3043, and the observations were obtained with the NASA/ESA Hubble Space Telescope operated by the Space Telescope Science Institute managed by the Association of Universities for Research in Astronomy Inc. under NASA contract NAS5-26555.Attached Files
