Abstract

The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) has provided unique near-infrared imaging in the 1 - 2 micron regime on the Hubble Space Telescope (HST) since its installation in 1997, with an enormous archival legacy of over 80,000 exposures obtained to date. Many of the images, however, are significantly dominated by artifacts that are a strong function of temperature and/or persistence effects. We describe a comprehensive program aimed at completely calibrating all the dominant temperature-dependent effects, as well as improvements in a wide variety of calibration-related software programs, that have enabled a full recalibration and reprocessing of all the NICMOS data obtained since its installation on HST. The resulting dataset has dramatically improved scientific quality and will serve as a valuable archival legacy that will also benefit future infrared instruments and observational programs.
