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.
