image.maxfit - Function

1.1.1 Find maximum and do parabolic fit in the sky

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 fitcomponents.
