Description:
Resample and co-add together FITS images
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.
