Chapter 19: Web-based tools-montage: An astronomical image mosaic engine
2008
Montage (http://montage.ipac.caltech.edu) is a toolkit for aggregating astronomical
images into mosaics. Its scientific value derives from three features of its
design:
• It preserves the calibration and astrometric fidelity of the input images to deliver
mosaics that meet user-specified parameters of projection, coordinates,
and spatial scale. It supports all projections and coordinate systems in use in
astronomy.
• It contains independent modules for analyzing the geometry of images on the
sky, and for creating and managing mosaics; these modules are powerful
tools in their own right and have applicability outside mosaic production, in
areas such as data validation. It can take advantage of SIAP services to discover
input images that meet the specifications of the sky coverage of the
output mosaic.
• It is written in ANSI-compliant C, and is portable and scaleable – the same
engine runs on desktop, cluster or supercomputer environments running
common Unix-based operating systems such as Linux, Solaris, Mac OS X
and AIX.
