Fitted slopes of individual pixels in the array, from the histogram above. Slope images are typically spatially fairly smooth, at least on this scale. Stretch is 10. to 35., the range of the histogram. Color mapping within the stretch is as described for the linear offset image. The constant term in the quadratic fits, for each pixel.
Information is the same as for the linear offset histogram described above.
Typically similar in form, except for a general shift to lower values. The constant term in the quadratic fits, for each pixel. Similar to the linear offset image, above, except typically shifted towards the blue. Stretch, color mapping, etc, are the same. Like the linear fit slopes, these are roughly 25, but shifted generally higher due to the overall curvature, which is downward.
