Stacking the images

When all the images worth of being processed are selected, select the "Stack" tab.

The reference image is displayed in the image frame ; draw a crop box around the planet or the area of interest in your image.
This box defines the area that will be kept in the final image.

You can select the double size checkbox to stack in a resulting image twice the size of the crop box. This will not add any information to your image, but as Lynkeos stacks each image with a subpixel translation, it can give a more pleasing result.

Press the stack button to start stacking.
When the stacking is complete, it is now time for the last step : process the stacked image.
