swarp - 2.41.5-1+b2 main

Resample and co-add together FITS images using any arbitrary astrometric
projection defined in the WCS standard. The main features of SWarp
are:
.
* FITS format (including multi-extensions) in input and output,
* Full handling of weight-maps in input and output,
* Ability to work with very large images (up to 500 Mpixels on
32-bit machines and 10^6 Tpixels with 64-bits), thanks to customized
virtual-memory-mapping and buffering,
* Works with arrays in up to 9 dimensions (including or not two spherical
coordinates),
* Selectable high-order interpolation method (up to 8-tap filters) in any
dimension,
* Compatible with WCS and TNX (IRAF) astrometric descriptions,
* Support for equatorial, galactic and equatorial coordinate systems,
* Astrometric and photometric parameters are read from FITS headers or
external ASCIIfiles,
* Built-in background subtraction,
* Built-in noise-level measurement for automatic weighting,
* Automatic centering and sizing functions of the output field,
* Multi-threaded code with load-balancing to take advantageof multiple
processors.
* XML VOTable-compliant output of meta-data.
