The result of how MARCI takes pictures leaves a filter height offset in adjacent filters. This will correct that offset
by adding padding to the top of the image file, aligning color images correctly.
The filters are offset by a certain number of filters, which is a multiple of their height. It appears
the filters are all offset by twice their height, or two filter heights. One filter height can be explained by
the method of taking pictures: the first filter on the first framelet is one higher than the second filter on
the first framelet.

Description
AUTO
Auto-detect whether or not this correction is needed
This option will look at the correlation between the first framelet's data and the second framelet's data.
If there is a better correlation between the end of the first framelet and the end of the second
framelet compared to the beginning of the second framelet, the framelets will be flipped. This only
correlates the first filter's data.
YES
Flip the framelets
On ascending orbits, the framelets are aligned incorrectly. This option will mirror the framelets to correct this problem.
NO
Don't modify original data
This will prevent any modification of the original data and should be used on descending orbits.
This is the command line for running this program with a typical EDR. FLIP should be AUTO, YES, or NO.

Running with default options
This is what the interface should look like when running this example with FLIP set to AUTO.
Output Images
Output Image
The output images (combined), using AUTO flip, cropped and colorized for this example
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 outputs, because MARCI takes long strips of data, this image was
cropped at line 2800 to a height of 1000 pixels. This image was created with FLIP set to AUTO, which decided to
flip the data.
Output Image Without FLIP
The output images (combined), using NO flip, cropped and colorized for this example
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 outputs, 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, because AUTO flipped the data. When you look closely, especially compared
to the flipped data, the features in this data are distorted.
