Task: zeefake
Purpose: Generate fake Zeeman data.
Categories: profile analysis

Key: iout
        The output Stokes I cube. No default.

Key: iuout
        The output Stokes I cube in the case of no splitting.  Default
        is not to write this cube out.

Key: vout
        The output Stokes V cube. No default.

Key: imsize
        The output cube sizes, all three dimensions required (VXY)

Key: vinc
        The velocity increment along the cubes in Km/s. No default.

Key: delv
        The Zeeman splitting (separation of split lines) in Km/s. 
        B   0 if DELV   0.
        No default.

Key: fwhm
        The FWHM of the Gaussian line profile in Km/s. No default.

Key: grvc
        The velocity increment of the line centre in the x-direction 
        per pixel (km/s).  Makes a linear ramp across the source.

Key: grint
        Intensity increment in the x direction per pixel. Makes
        a triangular weighting function.  Peak response is 1.0

Key: grfwhm
        FWHM increment in the x direction per pixel.  Makes
        a linear ramp across the source.

Key: grsplit
        Splitting increment in the x direction.  Makes a linear ramp
        across the source.

Key: theta
        The angle of the magnetic field to the l-o-s in degrees. No default.

Key: noise
        The r.m.s. noise to be added to the RR and LL responses. Note
        that the peak RR or LL response in this program is 1.0 for theta=0

Key: restfreq
        The rest frequency of your line in GHz.

Key: type
        The line type; "e" for emission (default) "a" for absorption
