Parallelization and algorithmic enhancements of high resolution IRAS image construction.
CAO Y., PRINCE T.A., TEREBY S. and BEICHMAN C.A.
Abstract (from CDS):
The HIRES program was developed by the Infrared Processing and Analysis Center (IPAC) to produce high resolution (∼1') images from IRAS data using the Maximum Correlation Method (MCM). We describe the port of HIRES to the Intel Paragon, a massivley parallel supercomputer, other software developments for mass production of HIRES images, and the IRAS Galaxy Atlas, a project to map the Galactic plane at 60 and 100 microns.
Images produced from the MCM algorithm sometimes suffer from visible striping and ringing artifacts. Correcting detector gain offsets and using a Burg entropy metric in the reconstruction scheme were found to be effective in suppressing these artifacts. A variation of the destriping algorithm was used to subtract zodiacal emission.
