HIRES

HIRES is a tool that allows users to produce higher spatial resolution images from archival data of the Infrared Astronomical Satellite (IRAS) by using the Maximum Correlation Method (MCM, H.H. Aumann, J.W. Fowler and M. Melnyk, 1990, AJ, 99, 1674). HIRES can be a useful tool for studying morphology, separating confused sources, and to do aperture photometry. It can produce spatial resolutions of better than an arcminute, roughly a five-fold increase over the unenhanced resolution. However, the actual resolution achieved for a given source varies in a complicated fashion. HIRES fluxes are accurate to about 20% and most of the uncertainty is due to background estimation uncertainties. Its images are available as 1 degree by 1 degree or 2 degree by 2 degree images, with either 15 in. or 30 in. pixels. The user also has control over what data goes into the image and what de-striping technique is used.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
