Description

This function finds the pixel with the maximum value in the region, and then uses function findsources to generate a Componentlist with one component. The component will be of type Point (point=T) or Gaussian (point=F).

If negfind=F the maximum pixel value is found in the region and fit. If negfind=T the absolute maximum pixel value is found in the region and fit.

See function findsources for a description of arguments point and width.

See also the function fitsky.

Example

- myim := imagemaketestimage()
- cl := myim.maxfit()
- cl.edit(1)                  # There is only one component
