What is Montage?

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

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