Aligning To A Single Image
When To Do
There are times when auto correlating on the first attempt produces terrible correlation (1 0 1 command produces barely any * next to images). This occurs when the topography shown in all the images is not defined enough auto. To fix this problem it is best to choose an image that has the best visible features , by visual inspection, and then have all other images align to that distinct image.
How To Do
The commands to enter from the lithos main menu are.
