Simplicity of usage and configuration. ffl Speed: typically 500 kpixel/s with a Pentium2@450MHz. Ability to work with very large images (up to 65k pixels on 32bit machines, or 2G pixels on 64bit machines), thanks to buffered image access. Robust deblending of overlapping extended objects. Real-time filtering of images to improve detectability. Neural-Network-based star/galaxy classifier. Flexible catalogue output of desired parameters only. Pixel-to-pixel photometry in dual-image mode. Handling of weight-maps and flag-maps. Optimum handling of images with variable S/N. Special mode for photographic scans. Modularity of the code that enables one to implement new parameters.
