Make a Complex image

Synopsis
makecomplex(complex, real, imag, amp, phase)

Arguments

complex	in	Output complex image file name
		Allowed:	String
real	in	Input real image file name
		Allowed:	String
		Default:	Unset
imag	in	Input imaginary image file name
		Allowed:	String
		Default:	Unset
amp	in	Input amplitude image file name
		Allowed:	String
		Default:	Unset
phase	in	Input phase image file name
		Allowed:	String
		Default:	Unset

Returns
T or fail

Description

This function generates a Complex image file from either a real and imaginary, or an amplitude and phase pair of images. If you give a linear position angle image for the phase, it will be multipled by two before the real and imaginary parts are formed.

Example

- p := imagepol('iquv')
- p.complexlinpol('qu.cplx1')        
-
- q := p.stokesq()
- u := p.stokesu()
- q2 := q.subimage('q')
- u2 := u.subimage('u')
- p.makecomplex('qu.cplx2', real='q', image='u')

In this example we make two complex linear polarization images which should be identical.
