Fit all 1-dimensional profiles in a region

Synopsis
fitallprofiles(region, axis, mask, ngauss, poly, sigma, fit, resid)

Arguments

region	in	The region of interest
		Allowed:	Region tool
		Default:	Whole image
axis	in	The profile axis
		Allowed:	Integer or unset
		Default:	Spectral
mask	in	OTF mask
		Allowed:	Boolean LEL expression or mask region
		Default:	None
ngauss	in	Number of Gaussian elements
		Allowed:	Int
		Default:	1
poly	in	Order of polynomial element

Returns
T or fail

Description
This function fits all of the 1-dimensional profiles in the specified region with a given combination of Gaussians and a polynomial. It makes a separate automatic estimate for each profile before making the fit.

Any masked input pixels do not contribute to the fit. The output mask is a copy of the default input pixel mask (if any); the OTF mask does not contribute. Any other input pixel masks will not be copied. Use function maskhandler if you need to copy other masks too. Use function calcmask if you need to apply the OTF mask to the output.

Example

- myim := image('gc.small')
- myim.fitallprofiles (axis=3, fit='gc.fit')
