Source analysis

There are several XIMAGE commands to make a detailed analysis of the image. These include:

• SOSTA - calculate the source counting rates and statistics correcting for vignetting, point spread function and exposure,

• BACKGROUND - estimate the background.

• DETECT - a sliding cell source detection algorithm, using the PSF and vignetting to estimate source significance and statistics.

• REMOVE - remove sources from an image.

• PSF - generate a point spread function, and compare it to the predicted psf.
