Slower than celldetect. Finds extended sources well. Finds faint low surface brightness features. Combines closely spaced point sources. Extended sources found as single source in visually 'correct' way, regardless of their actual shape.
Combines diffuse emission with embedded point sources.
Slow for more than photons. In this section, we provide a brief description of each tool and the most minimal instructions on how to run the software. Chapter 2 contains the more extensive discussion needed for general use with examples for each method and a short discussion of the primary parameters. For a complete description of all parameters and the data products, see chapter 9 . In the former, the background is estimated in a frame around the detect cell and in the latter, a background map is required.
