Changes in offsets during an exposure set

In the engineering regressions, a set of four exposures is taken at each position. The following histograms show how much
the offsets shifted in between each exposure taken in a set.

RA offset deltas (difference in value between two adjacent exposures) for June and July

June, left to right: Difference between first and second exposure, difference between second and third exposure, difference between third and fourth exposure.
July, left to right: Difference between first and second exposure, difference between second and third exposure, difference between third and fourth exposure.

The changes are smaller in July, this could be attributed to the lack of AOS correction during that regression.

Declination offset deltas (difference in value between two adjacent exposures) for June and July

June, left to right: Difference between first and second exposure, difference between second and third exposure, difference between third and fourth exposure.
July, left to right: Difference between first and second exposure, difference between second and third exposure, difference between third and fourth exposure.

The changes are smaller in July, this could be attributed to the lack of AOS correction during that regression.
