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
- Scaleability:
- 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 min 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
News

- IRSA and the NVO announce an on-request mosaic service. The service runs on a compute cluster and uses Montage to return mosaics from 2MASS, SDSS and DSS.
- January 5, 2007

A view of the Rho Oph dark cloud constructed with Montage from deep exposures made with the Two Micron All Sky Survey (2MASS) Extended Mission. The deep exposures were 6x longer than in the main, all-sky survey and cover 70 square degrees of the sky in 30 areas. Mosaics were made for all of these areas by 2MASS to show the spatial coverage and content of the deep exposure images. The mosaics are published as part of the documentation for the Extended Mission.
