Below we see the two different release dates of the GLB.Ts-2005-08 and GLB.Ts-2018-01.

There is a slight change at the back end (1880 side) and the front end (2005 side).

 

We can take the difference from the past to the present.

To show the change as a regression, we added a wave analysis.

 

Looking at the wave analysis, there are points where the data clearly diverges both down and up from the past release in 2005.

Anomaly data after 1970 has been altered up from its original release.

 

In our Reset post of this data, we removed this alteration.

Additionally, given these referenced links, we made further adjustments to arrive at the approximate values we posted.
