What is Montage?

Montage is a toolkit for assembling Flexible Image Transport System (FITS) images into custom mosaics. Key features for end users are:

Preserves spatial and calibration fidelity of input images
Runs on all common Linux/Unix platforms
Runs on desktops, clusters and computational grids
Open source code and user documentation available for download
Supports all World Coordinate System (WCS) projections and common coordinate systems
Processes 40 million pixels in up to 32 minutes on 128 nodes on a Linux cluster
Independent engines for analyzing the geometry of images on the sky; re-projecting images; rectifying background emission to a common level; co-adding images
Tools for managing and manipulating large image files
