With COS3, it's a modified version of the 12225074 OS yes?Would there be much involved in modifying the XDF for this to work with COS3?

First, a couple of assumptions. That you already have an accurate XDF for 12225074, and that this XDF also correctly calculates the segment Checksums.

Then, you would need to determine which parameters in the XDF are no longer used by the COS, and delete these parameters from the XDF.

Then, you would need to determine which parameters in the XDF have been altered (rescaled or repurposed) by the COS, and adjust the definition of these parameters in the XDF.

Then, you would need to locate and define all of the new parameters in the calibration created by the COS, and add these new parameter definitions (flags / scalars / tables) to the XDF.
