Input Image

Output Image Without FLIP

The input image, not flipped, cropped and colorized for this example

Output Image Without FLIP

Since this particular input image had a RED, GREEN, and ORANGE filter, it was possible to display the image in color. To give a better picture of the output, because MARCI takes long strips of data, this image was cropped. In order to show the same feature as the flipped image, the crop was at line 5800 to a height of 1000 pixels. This image was created with FLIP set to NO in marci2isis, because AUTO flipped the data. When you look closely, especially compared to the flipped data, the features in this data are distorted.

Output Image

Since this particular input image had a RED, GREEN, and ORANGE filter, it was possible to display the image in color. To give a better picture of the output, because MARCI takes long strips of data, this image was cropped at line 2800 to a height of 1000 pixels. The distortions in the original image are now gone.
