This should be the base filename of resultant cube. The output will actually be two cubes, with "even" and "odd" added to the filename.

Settings: COLOROFFSET

Description

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.

Default true

Settings: COLOROFFSET_SIZE

Description

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

This corrects pictures taken on an ascending orbit

Type string
Default AUTO
Option List:
Option Brief Description
AUTOAuto-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.
YESFlip the framelets On ascending orbits, the framelets are aligned incorrectly. This option will mirror the framelets to correct this problem.
NODon't modify original data This will prevent any modification of the original data and should be used on descending orbits.
