Description

Tilt is instrument artifact of THEMIS that is due to temperature variation across the calibration flag. This artifact becomes apparent once an image has been stretched by a decorrelation stretch. It shows up as color change that is variable over the whole image and generally changes from the left side to the right side of the image. rtilt() will remove this effect.

The image on the left first shows the tilt as a bright blue color which later changes in the image to a green color. The right image has had rtilt() applied.
