? Explanation on each of the menu options

COLOURS Choice of different colour tables e.g. grey scale, inverse grey scale (black is more intense), ``temperature''. Several of the different colour tables are shown throughout this paper.

GRID Add or remove horizontal and vertical grid lines to the image display

POSITION Change the position for the image display in the graphics window

ROTATE LUT Change cyclically the colours used to display different intensity levels. This can emphasise different features in the data.

TITLE Change the title of the image.

X-AXIS LABEL Change the text used to label the X-axis of the image.

Y-AXIS LABEL Change the text used to label the Y-axis of the image.

Z-AXIS LABEL Change the text used to label the intensity scale (Z-scale) of the image. This is drawn with the look-up table intensity scale

Z-SCALING Change the mapping of data values to pixel colours (see Section 3.8 for further details).

ASPECT RATIO Change the ``aspect ratio'' for image display. By default pixels are drawn square, so if the ADR is rectangular the image is rectangular. When many more pixels are defined in one direction than the other, it can be more useful to allow the pixels to be rectangular and allow the image to fill the full region available. These modes can be toggled.

NO LUT Don't draw the ``look-up table''. When clicked, this is replaced by the button DRAW LUT.
