This task create an image which can be read from a file or created
from a function. The ouput filename is FILEO$.
A- From a FILE: if the logical variable IFILE$ is set to YES an image
is read from the input formatted file FILEI$ the column must ordered as
: x y z and expect to have standard gdf image structure. For conve-
nience, z should be in Brightness temperature, as for B case.
B- From a FUNCTION: If one of the function is activated a corresponding
image using the parameters PARAMETERS$ will be created. Intensity are
in Brightness temperature.
E_DISK : Elliptical Disk
E_RING : Elliptical Ring
E_GAUS : Elliptical Gaussian
E_EXPO : Elliptical Exponential
RECT : Rectangle
POWER : Power law
PLAN : Plan
Convertion to Jansky is possible if variable JANSKY$ is set to YES. The
image can be mutiplied by a gaussian beam if BEAM$ is set to YES parame-
ters are similar as for function GAUSS.
ONLY ONE function can be computed at the same time, Nevertheless more
complex images can be produced using both CIMAGE and COMBINE tasks.
