The parameter panel of the Rendering Module controls most of the settings that are relevant from an observers point of view. It is divided into different sections. For a detailed description of these sections click on the links below or on the appropriate region on the clickable map at the top of the page.

Images:
With the image parameter tab on the Render Module you control the extend of your image on the sky. It also allows you to set the image resolution, i.e. the FWHM of the gaussian point spread function, as well as the spectrograph slit parameters.

PV diagrams:
The panel for the PV diagram controls the parameters of the wavelength axis in terms of velocity in km/s.

Rotation:
The parameters in the Rotation panel control the viewpoint and orientation of the observer or camera with respect to the object.

Rendering:
In the rendering tab you select and set the parameters of the different renders that are available. Which one to choose depends on the particular problem that you are modeling.

Units:
The units setup controls how the generic units of the 3D Module map to physical units on the sky, e.g. arcsec, meters, parsec, etc. The distance to an object is also set here.

Measurements:
The measurements tab gives access to a device that allows you to measure distances, angles and velocities in your rendered model or observed images (after they have been loaded into Shape)..
